I'm not sure about whauk's post, but maybe he means the longest row of steadily increasing times?

Here's a new question: has anyone ever won every round in a competition (which had more than one round)? If so, what was the competition with the most rounds where this was done? If not, what was the highest percentage of rounds anyone has won in a competition?

cubernya · Jul 28, 2011

Well I'm sure Feliks beats everyone in that qq

qqwref · Jul 28, 2011

I'm not.

EDIT: Looks like Feliks won everything here. So that's probably the record then. (But what's 2nd?)

Well, this is probably 1st place: http://worldcubeassociation.org/results/c.php?i=SESCSantos2011&allResults=1#333

(and he didn't do really well that day...)

EDIT

Well, your first question was about "every round", but I'm not sure if that means every round in the whole comp or every round in the same event...

EDIT 2

Nah, "every round in a competition" is pretty clear...

I've won a lot of stuff in the past:

10/11 (90.91%) - http://worldcubeassociation.org/results/c.php?i=MinasOpen2008
5/7 (71.43%) - http://worldcubeassociation.org/results/c.php?i=BrazilOpen2007
10/15 (66.67%) - http://worldcubeassociation.org/results/c.php?i=ABCOpen2010
8/13 (61.54%) - http://worldcubeassociation.org/results/c.php?i=SaoPauloOpen2009
7/12 (58.33%) - http://worldcubeassociation.org/results/c.php?i=SantiagoOpen2009
10/18 (55.56%) - http://worldcubeassociation.org/results/c.php?i=UNESPOpen2009
8/16 (50%) - http://worldcubeassociation.org/results/c.php?i=BrasiliaOpen2009

But not recently: 5/17 (29.41%), 6/15 (40%) and 1/17 (5.88%)

(I'm not counting the 4x4 bld with everybody DNFing)

Weird: This person doesn't have a gender.

I've searched the top 100 single 3x3 solves, and found only 2 female cubers:
This girl has 9.13 solve and she has a 8.63 solve. I was just looking because I know a girl who hasn't competed yet, but might get our next Belgian record.
Stefan, could you check if I missed someone? My SQL-skills have probably died out, and I also don't know where to download the WCA database (if this is available for everyone).

One of 454 persons where the database doesn't know it, nothing special.

You know, they do have names.

Next fastest is Patricia Li with 9.69 and there are no others with sub10 solves.

I just noticed that the top 100 people in 3x3x3 BLD are all now sub-1:30. (I think I remember predicting we'd get here about a year and a half ago. Yeah, I guess I'm not very good at predictions.)

I wonder how long it will be before the top 100 are sub-minute? (Currently there are 33 who are sub-minute.)

RyanReese09 · Jul 29, 2011

I give it 2 more years.

History looks roughly like this.

Based on that graph, I'm guessing in 1.5 years, beginning of 2013.

The top seven 3x3x3 singles are by the same dude.

What is the best 3x3 SD, between first 100 results, removing best and worst time?

MAHTI-ANSSI · Jul 31, 2011

Now the top 100 official 3x3 average results are sub-10.

Talking with Dave I mentioned that China is pretty good at memory competitions, then Dave said they're pretty good at many things, then I said it has to do with them being so many, and that it helps even more in team games because it's not enough to happen to have one good player. Then we translated that to cubing. Which country is the best, judged by the average of their top 10 cubers (3x3 average)? Again, it's not enough to happen to have one good player, so Feliks can dominate all he wants but Australia is still nowhere near the top

For the write-up, I tried to reconstruct how we started this conversation, and Dave found it ironic that I couldn't remember that I had started it by talking about memory competitions. Pfft.

but in terms of per capita... Well all I can say is america is definitely not at the top then

Very cool post. This is also a pretty good indication of where cubing is most competitive.

Any way we could see average age by country?

Stefan · Aug 8, 2011

ltsurge said:

It definitely is! USA shares first place with every other country as all countries are getting DNF.

DavidWoner said:

Can't do it right now, but it should be fairly easy. Something like:

SELECT countryId, avg(datediff(now(),year*10000+month*100+day))/365.25 avgAge
FROM Persons
WHERE day>0
GROUP BY countryId
ORDER BY avgAge

ltsurge said:

Btw, with judging by top 200 instead, USA still leads but China moved up to second place, and judging by top 300, China is on top. Don't know the exact point where they switch, and they might also switch back and forth several times. And maybe at some point some third country would be on top, haven't checked that, either (well, judging by top 1, obviously "Australia" wins).
