Odd WCA stats/ Stats request Thread

I don't know how to word this in a good way, but what is the most number of different competitors a single competitor has shared a comp with?

Prediction: Ron van Bruchem (6636.)

When I ran this stat back in March, Ron was 5th. First was Ming Zheng with 7220. I'll run it again when I get a chance because I'm actually curious how it's changed. Some really big comps this year (Worlds, US Nats, China 10th Anniversary) could have made a big impact.

2 ends of a spectrum here,

Which 2 competitors have been to the most competitions together? And how many comps is that?

Which 2 competitions have the largest group of cubers in common? And how many cubers is that?

Competitors sorted by number of people they've been to competitions with. The number you want is the first number in the distribution list.

Are the subsequent numbers in each distribution the numbers of people with minimal distances of 2, 3, etc. from the competitor in question?

Yes, they are.

 

[JustinTimeCuber]

Everyone with a faster 3x3 average than me has a faster single.
Yeah, all 346 of them. Interesting stat.

I'm wondering how many people can say this?

 

[applezfall]

how many people with a slower 2x2 average then me have a better single than me (a lot probably)

 

[GenTheSnail]

I'm wondering how many people can say this?

Well, it is a pretty crappy single

Everyone with a faster 3x3 average than me also has a faster sequence of 5 solves such that the mean of the middle 3 are faster than my average.

 

[JustinTimeCuber]

how many people with a slower 2x2 average then me have a better single than me (a lot probably)

*raises hand*
2.80 avg, 1.97 single, so barely on both ends

 

[thecubingwizard]

What is the largest magnitude of the absolute value of the difference in World Single ranking and World Average (or mean) ranking for all events, given that the person has results for both single and average in that particular event?

I just found a good candidate: 2009RUSE01 is #5739 WR 2x2 single (3.08 seconds) and #45843 WR 2x2 average (26.98 seconds).

 

[Linxiao]

Sorry if someone else already asked this but has anyone got a WR/CR/NR single for his/her solve then get another WR/CR/NR single in the same average? E.g. Oliver Tafunai of Samoa has got a 36.95 (NR) for his 1st solve, then got a 27.05 (another NR) for his 2nd.

Just saw this post.
In Shantou Open 2014, Xiao Hu broke the single AsR of skewb at the second attempt, and then tied that score at the fourth attempt.

 

[James Hake]

idk if this is the right thread for this, but so far the three people with 5.xx sq1 singles dont have any 6.xx singles

 

[whatshisbucket]

Charlie has a 6.89.

 

[James Hake]

Charlie has a 6.89.

ah, i just saw that

in that case, all three got 5s before 6s
