1:14.41, 1:14.09, 1:15.53, 1:21.43, 1:14.81,

Right?
With 3x3 WCA used the format "mean of" instead of "average of" to calculate the standard deviation. So your SD should be higher.

At a competition last year i had .60 standard deviation on 6x6.

3:36.65 3:35.55 3:35.68

didnt someone with magic get 5 solves with the same times

 

[cuber952]

isnt that .49

I typed them into QQtimer to find it. I don't know how to calculate standard deviation so i can't check it

I calculated my SD with QQtimer, so I don't know it's the the correct SD.

qqTimer usually use format "avg. of" to calculate SD.
Probably your SD, should be over 1.00 if we count all times.

At the moment i don't know if your SD with 5 times is the lowest (probably not); but i know that also your SD with 3 times isn't the lowest (Giovanni had a 0.2x SD), and i don't think that is the best.

I would like to see a list of the youngest and oldest people getting a NR (at least; CR or WR by extension). I don't know whether this is difficult or not, but I would really appreciate it. (Disregard single records and focus in average records, if you find it easier.)

 

[oranjules]

there isn't the age on the downloadable WCA database, so it's impossible for us to do :/

 

[Luis]

I was told that some people have access to such info.

Thank you very much, Stefan.

An off-topic question.
Supposingly, the name ธีธัช จารุวัฒนกุล is given in the Thai alphabet and transliterated (not transcribated as e.g. Chinese names!) into the Latin alphabet as Theethat Jaruwattanakun. It seems locical that Greec, Russian and other names should be treated in the same manner.

Yes, here's Russian Ilya Pankratov (Илья Панкратов).

 

[oranjules]

and is it possible to have the same list for world champions ?

 

[JackJ]

Here's a weird one:
Me and Yu Nakajima,
both tied at one point with 8.72 single in 3x3
now tied with 8.91 average in 3x3
first sub10 avg by each of us: 9.96
first sub9 avg by each of us: 8.91

has anyone else ever been tied with someone for both single and avg? Even at the same time? For any event?

From Feb '10 to April '10, Quanhui Li and I both had 23.09 singles and 25.20 averages. Both these times were set in the same round too.

 

[MalusDB]

I wonder how many people have nobody else in the rankings having any of their names individually? As in I am Eamonn Neeson, and there is nobody called Eamonn or Neeson regardless of their other names. I doubt it's that rare really but I just searched to see if there was another Eamonn and I'm all alone ( or at least will be after I compete at the Irish open this spring!)

 

[Rune]

Yes, here's Russian Ilya Pankratov (Илья Панкратов).

Should the answer be taken as a joke?

No, why? I just showed that indeed it's no problem for our software. If we get the native names of others, we can display them as well. I think the delegates were asked to collect and send us lists, but I don't know the progress of that.
