So wrong word. Did I do the math wrong though?

[WR] Feliks Zemdegs 3x3 OH single 6.88

Come back with better math.

Replies like this are part of the reason that students in my college algebra classes hated math, and hated answering questions in class. If there is something wrong with the math, then have the decency to point it out.

Examining 2 sides: 17.61 seconds/cube
Examining all sides: 24.41 seconds/cube

Examining 2 sides case:

1 scrambler * 17.61 sec/cube * 5 solves/competitor * 80 competitors * 1hr/3600seconds * 1cube/1solve = 1.9567 scrambler*hours
With 2 scramblers that's 1.9567 scrambler*hours / 2 scramblers = 0.9783 hours which is approximately 1 hour duration, using 2 scramblers, to scramble 5 solves per competitor for 80 competitors.

Examining all sides case:

1 scrambler * 24.41 sec/cube * 5 solves/competitor * 80 competitors * 1hr/3600seconds * 1cube/1solve = 2.712 scrambler*hours
With 2 scramblers that's 2.712 scrambler*hours / 2 scramblers = 1.3561 hours which is approximately 1.35 hour duration, using 2 scramblers, to scramble 5 solves per competitor for 80 competitors

Checking only 2 sides:1 hour
Checking all 6 sides:1.35 hours

As a quick back of the napkin calculation I confirm biscuit's results for the total scrambling time using two scramblers under the two scenarios. Whatever conceptual mistake you think biscuit has made, it is not readily apparent so please provide a more detailed reply as to the nature of the error than "Come back with better math"

I'm still not convinced by the calculations myself -- If enough cubes are called up and the scramblers get ahead so that there are still cubes to be taken, then checking extra faces is essentially "free" time. Scrambling time isn't the only logistical constraint, running/solving time also constrains the time on competitions. I almost always check all faces of the cube and I don't feel like I'm dragging competitions behind that much.

I'm wondering if this calculation functions as an estimate of the lower bound of the duration of a round.

The WCA should implement something to cover in situations like this. I think he should get a +2 because it was not his fault but yet he could have received an advantage.
Yes, he is a really good cuber, but I am sure he would have gotten a worse time with the other scramble.

You can't possibly know that. He PROBABLY would have but you can't know that... He could have been even faster on that scramble

LOL...at 0:46 seconds in the video, Jayden McNeill couldn't take it anymore and had to leave.

 

[Ross The Boss]

im a bit amused with feliks' autograph on the score card. every other solve is signed with a relatively clean FZ (F2 ), but his record signature is just a bunch of squiggles. it seems he was quite excited

 

[Goosly]

Lol. Not sure if serious or just trolling.

Again, this touches on the issue of using video evidence only to punish. Everything was assured to be accurate by the scrambler, the delegate signed off, and only the video evidence raised suspicion. This would have gone through without any suspicion if no one had filmed it. Feliks is lucky that he still has the WR that he earned, but he had every right to hide his personal video, and there would have been little the WCA could have done about it.

If a mistake makes it past the competition, video should NOT be used as a method for retroactively DNFing. Either that or every WR should require video. It's about a fair, equal playing field.

To make it even more fair; if a competitor gets a mis-scramble with a unfavorable solution he should gain 2 seconds (-2) because of an unlucky and disadvantageous mis-scramble

This was not done when it was shown via video review that Drew made a turn in inspection in what would have been a wr average.

Let's say he somehow managed to put the scrambled cube in his pocket and pull out a solved cube from another pocket without anyone at the competition noticing and stops the timer at a world record time. He uploads a video where the cheating is clearly visible but we shouldn't DNF the solve because it would be unfair. Seems about right.

 

[newtonbase]

If video evidence is available then I think it should be used. You can't pretend it doesn't exist. Imagine how tarnished this record would be if the WCA had refused to look at it. Fortunately they have looked at it and have, IMHO, made the right decision.

This is the the best ever OH solve done by the best ever cuber and I hope we can look back at it as such as it's likely to be the record for quite some time.

you can make extreme examples, but look at the situation in Mexico a few years ago. There was no video evidence and they were still able to determine, based on the cuber, and the situation, that he definitely cheated. Feliks is not a cuber who needs to cheat to attain world records.

Honestly, I would rather just have every WR require video (other than FMC). I don't want to stray too far off topic though. I made my case long ago, and more people disagree with me than agree with me, which is fine. If people are happy with the current system, then there's not much more to say.

Ok sorry I don't know for sure, but that is the logical conclusion.

Lol. Not sure if serious or just trolling.

Well, the way I feel about that is that he should not be DNF'ed because someone else was responsible for the mistake.
However I feel that he received an advantage (therefore it should not be counted as a WR).
So give him a +2.

Slippery slope is slippery. Your scenario is obviously absurd, when people cheat they usually try to conceal the fact that they did, they don't upload videos of them doing it for everyone to see. People who upload videos of official solves don't seem to have anything to hide, yet it seems like right now they're getting punished for doing so because of the laziness of others. I like DeeDubb's idea, right now it feels like there's a strong incentive not to video yourself if you're good enough to break a record, and that's a really bad thing.

Wow... shaved off the former WR by almost 2 secs... poor Haixin Zhang... amazed that there's 35 pages of posts in 2 days...
