Behind Team USA (+FOB): The Team that Brought You Worlds 2013

I remember not being convinced it would help much the first time we used the runner system back in '06(?), but it really would not have been possible to do a 600 person competition on 24 timers in three hours without it.

If my memory serves me correctly (it does), we actually burned through 3x3 in two and a half hours :tu (although if you take out staff it was closer to 500 I think).

(many could have been ahead, but I did not call up any heats more than 2 minutes early for the main stage)

Darn you and your cellphone running 30 seconds behind my watch >.<
 
This would work if you had dedicated scramblers to each timer. Otherwise, the runner has to keep track of which cubes to bring to which timers, which is much more taxing and prone to mistakes. It's much easier to call "ANDREW RICCI, 6."

I should note that for the staff round 1 heats, it was much easier for us to pair up and get each other through (on different sets of scrambles) on the same timer for certain events where scrambling was easy (e.g. 2x2) than to have the runner/scrambler system, because the latter takes a bit more effort to set up.

One thing we did once was having a piece of paper with the timer number attached to the cube cover. That way the cube would always go to the same station, and the person would react and go to the timer quickly. But I think we kept people seated on the timer until they did all 5 solves. But it could work with rotating too. Of course that works a LOT better on later rounds, where people have about the same speed. As I said, if it's a huge first round, with times ranging from 10 to 150 seconds, that's not the best option.

Regarding cube covers, what did you guys use? How many of them? I saw black and red covers in the final. Was it divided by colors too?

Good input on the rotation. I could see that working in theory - I'm not sure how efficient it would be without doing some experiments and dry runs.

Cube covers were matched to stage colour - red/red, blue/blue, green/green.

Oh...it's green. It looked like black in the cubecast transmission, though. But what are they made of? Where did you get them?

We usually have just one stage (biggest so far was 14 tables), but we try to make 2 rows, one being a little taller than the other. And we use different color covers (they're actually plant pots like this) to separate which cubes go to the top or bottom row.


I forgot to ask about the multi bld, big bld and FM. I'm pretty sure it was a separate room. How was juding done there? I saw Eric Limeback using a music stand for his multi, but I guess not everybody was comfortable with that. Did you give people the chance to choose? How many judges were involved?
 
It's important that the person who announces the cube be loud enough that they can be heard by the competitors and understood. This was done pretty well this competition.

Some crazy ideas for improving heats: How about having some identification of the box hiding the cube so the cuber knows that his cube is up. For example, if you had enough boxes that you had one for each competitor in a heat, you could number the boxes and the box would stay with the competitor for the heat. This would eliminate the moving around of boxes that I noticed took some effort. And instead of announcing the (possibly difficult to pronounce) name of the competitor, you just announce their number and hold up the box. The competitors in a heat know their number. And when the competitor misses the call and the box ends up at the judging station, now the competitor can look at the box and see that it's his number. So he goes over there and solves without having to ask. I also like the idea of having the competiton slip be somehow attached to the box so it doesn't get lost. You could do that by adding a clip to the box.

I think this would not work at all in practise. The first major problem is that many competitors don't pay attention to boxes going up to the solving stations. They're chatting to their friends or practising solves while they wait. The second problem is, if this were to work, competitors would have to be watching boxes, which would eventuate in competitors watching the scramble table, which is definitely not what we want. The third problem is keeping the right cube with the right box, which could easily get mixed up and throw everything out of whack. The fourth problem is the de-personalisation of things by turning competitors into a number; names might be hard to pronounce, but learning how to pronounce them is a good way to introduce yourself to people. Also, assuming it is experienced competitors running and judging, and assuming it is new competitors with the names no one knows how to pronounce, it would be a good way for experienced competitors to get to know the up-and-coming generations.

As to your final note, the issue with this is the slip needs to be written on for each solve. So the slip would have to be detached and re-attached to the box every time. I don't see this working in practicality. Simply putting the slip inside the box alongside the cube works fine.


Sorry to throw your ideas completely down, but I think "crazy" was the right description :p

In theory, there shouldn't be much effort in moving around boxes. Runners bring back a box with a solved cube, so after scrambling there should be boxes available for it.

FMC was done in several rooms with 1 or 2 judges for each room. It's not too hard to judge since the ways to cheat are pretty blatant.

For multi-BLD, there was the option of using music stands or harmonica holders with a paper sheet. One judge was in charge of 4 competitors. Similar to the main events, there were scramblers and runners as well (maybe 2 of each). I believe there was somewhat of a heat system so that we would expect a few competitors to show up every 15 minutes or so.

~1 judge per 3 competitors, not including a few scramblers. We got to the point where 1 judge would be responsible for watching ~4 competitors at 2 adjacent tables, and a couple judges would 'run', meaning getting competitors started, helping arrange music stands, etc.

Competitors had the option to use music stands or harmonica holders. If used correctly (as by Shelley in that picture), the harmonica holders tend to be particularly effective. However if a competitor uses either option incorrectly (like here), this sucks up unnecessary staff resources (notice the extra piece of paper being held).

But did someone not use either option? How would that work if, for example, 3 of the competitors at a judge's table chose not to use?

Oh, another thing (sorry for being kinda annoying...).

Did you have 8 cube covers per heat, (i. e., cubes gets out of box to be scrambled, and only goes back into box when a solved one arrives) or each cube had its own cover at all times?

We never tried having cubes floating out and into covers, but that may save quite a bit of resources (and also require a bigger organization at the scrambling tamble, which is not always that big).

There were more covers than cubes so there was always a cover for a scrambled cube to go into.
 
Hmm...I'd think you only need the same number of cubes and covers, no?

Re-reading James' post

So that means they only had those 2 choices? No option for "I just want a judge to hold the paper"?
That sounds nice (from an organizing point of view)

Thanks for replying.

I'm not suggesting changing the system, I'm suggesting adding a very simple layer of redundancy. Redundancy is how engineers design safe systems. I've made a good living doing this for longer than you've been alive.

<<The first major problem is that many competitors don't pay attention to boxes going up to the solving stations. They're chatting to their friends or practising solves while they wait.

Also, assuming it is experienced competitors running and judging, and assuming it is new competitors with the names no one knows how to pronounce, it would be a good way for experienced competitors to get to know the up-and-coming generations.>>

I'm not suggesting a change here. The names still get called out. Let me spell it out:

(0) When the heat is called, the competitor drops his cube and his paper into a box. If he can't hear too well, he might want to remember the color of the box so he can recognize his box sitting lonely by a judge later, in the event he misses his name being called.

(1) The box is given to the scrambler. The scrambler examines the paper to determine the appropriate scramble and applies it to the cube. The scrambler puts the scrambled cube, with paper, back into the box and hands it to a runner. The runner shouts out the name and drops the box at an empty judge.

(2) The competitor hears his name, or notices his color box next to a judge. He goes up and solves. After the last solve he leaves with his cube. The judge puts the paper (and possibly the cube) back in the box. The runner picks up the box and if there's a cube in it, takes it to the scrambler, and if there's not, takes it to the place where the completed papers are kept.

<<The third problem is keeping the right cube with the right box, which could easily get mixed up and throw everything out of whack.>>

Most people will simply wait for their name to be called and so this won't effect them. But now that you mention it, it's possible for the wrong person to respond to the calling of a name (as well as the color of the box). But with two pieces of information, box color and name calling, the chance of this happening should decrease. This is the advantage of redundancy.

So has anyone ever sat down to solve and discovered that the cube under the box isn't their cube? And that the piece of paper doesn't have their name on it? I would think that this is something that already happens every now and then. If this is a problem, you need to have the judge read the name off the paper to the competitor when they sit down. As in "Carl Brannen, are you ready?" If they're not Carl Brannen, now would be a good time to fix things *before* the competitor discovers that the cube doesn't seem to turn like it used to and that his name isn't on the paper.

As it turns out, I've scrambled cubes at a competition. It was a wonderful way of learning how other people's cubes feel (and how clean their hands are, LOL). The cubes come in sitting on their corresponding paper but the two don't always stay together. This results in the question "whose cube is this?" Having the cube put with the paper in a box seems to me to make it more likely that the cube stays with the paper which is the important thing.

Having extra cube covers is safer. Plus we've had some cube covers being destroyed in the process (I have no idea how...) so we were fortunate to have a lot more cube covers than cubes.

We made exceptions for those who did not want to use music stands or harmonica holders, but these competitors would have to let us know in advance, and also not take too long, otherwise too many of these requests would drain the amount of staff we had running the event.

I don't like the idea of competitor's dropping cubes into boxes. This opens up the possibility of cheating by dropping a pre-scrambled cube into a box.

(1) The box is given to the scrambler. The scrambler examines the paper to determine the appropriate scramble and applies it to the cube. The scrambler puts the scrambled cube, with paper, back into the box and hands it to a runner. The runner shouts out the name and drops the box at an empty judge.

The easiest way to figure out which cubes need to be scrambled is to remove them from the box. Having both scrambled and un-scrambled cubes in boxes often leads to runners bring up un-scrambled cubes.

The cubes come in sitting on their corresponding paper but the two don't always stay together. This results in the question "whose cube is this?" Having the cube put with the paper in a box seems to me to make it more likely that the cube stays with the paper which is the important thing.

I haven't seen any issues with the cubes and paper being separated. At least with the national team, this doesn't seem to be an issue we currently have.

Funny that this is how we pretty much always do it. Of course there's always a person next to the boxes (the person calling people, mostly) to make sure people don't put scrambled cubes in there. We once collected all cubes on top of the scorecards (back in 2009), but that got a little messy.

Me neither. As you said, the cube comes inside the box, and we check the paper, take the cube, apply scramble, put it back. I guess maybe heavy wind or dropping the cover could lead to confusion, but that's not that common.

Hm, yeah we've been doing cubes on top of score cards in the US. This also helps in keeping scrambled cubes separate from un-scrambled cubes since the new dropped of cubes are not in boxes. What got messy when you tried it?
 
lots stuff

I can see where you're coming from, but I still feel that, at the very least, problems two and three that I brought up still apply (problem four is a more general thing which we can put to the side).

Now to be fair, problem two is already something that can happen with competitors looking out for when their cube is getting scrambled. However having colour-coded boxes can only add to the problem if it already exists...

As for problem three, the issue is scramblers getting boxes mixed up. In the original scenario, it would only be possible for a scrambler to match up the wrong cube with the wrong scorecard. In your new scenario, it is also possible to mix up the wrong cube with the wrong box, which would only lead to confusion further down the track.

Also another problem occurred to me (I should do this for a living, I bet I could get paid good money to find all the problems with ideas people come up with :p ). Problem five is that competitors will forget which box they put their cube in (let's assume the boxes are numbered rather than coloured, as having many different colours is logistically difficult and would lead to having similarly coloured boxes). It would be easy for a competitor to be waiting for box #3 to show up, only to realise later that they put their cube in box #3 in the previous event, and actually had #11 this time.

In a nutshell, I can see how redundancy would be good, but in this case it would just add confusion and more ways for things to go wrong rather than aiding the system. It would be good if we could come up with more ways to make the system work better, and you could be onto a good thing here. I would think about it some more, but it's almost 2am, I am tired, and I have a long flight ahead of me tomorrow so my brain has been switched off for the next few days :p

Well, basically we collected all cubes at once (around 50), so it was kinda messy. Now we only get cubes for each heat, and I usually make heats that are bigger than 2*timers. That way, once someone is done with the 5 solves, we just call another person, since there is now a free cube cover.

I don't see how scramblers would mess up the boxes (except for the cases I mentioned before).
I know the whole process can have a lot of differences around the world, but here's how it works at "my" comps:

1 - Get scramblers, judges and runners set up.
2 - Get the cube covers, lay them on a table, and start put scorecards into them and calling people.
3 - Competitor puts his *solved* cube into the cover which has his scorecard and goes to table/waiting area (this depends on wheter we have space for a waiting area or not).
4 - Someone (runner or me or someone else helping) takes covers which already have a cube inside to the scrambling table and people start scrambling
5 - Runner takes scrambled cubes to judges
* solving solving solving*
6 - Once cube is solved, scorecard filled and signed, runner takes the cube inside the cover back to the scrambling table.
7 - Scrambler takes one cover, checks scorecard to see which scramble to apply next, does that and puts cube back into cover.
go back to step 5 until someone is done with the solves.
8 - Once someone is done, the cover returns to scrambling table with only the scorecard inside (obviously)
9 - The MC/announcer takes the empty cover, places a new scorecard inside and calls the next competitor
REPEAT UNTIL EVERyBODy IS DONE (sorry, the y key is failing on my keyboard)


Another question to the US-WC-people:
How was the stage phisically set up? I mean, where was the scrambling table located for each colored stage, and where was the competitors waiting area?
