If your get 3:00, DNS, DNS in BLD, would it be a 3:00 mo3? No.

3:00, DNF, DNF that would clearly be the case, but with DNS, and averaging from competition to competition I don't think it's so clear. Should you be charged with a DNS if you go to a competition that offers the event but you don't register for it?

 

[mycube]

Do the running official FMC averages of 12, 50, 100 count DNS's as DNF's, or just ignore them? I ask because I have 3 DNS's in my last 6 attempts, since I could not be there when the attempts were done. If I pretend they never happened, then I have a 31.6 average of 12, but if they're DNF's, then (obviously) I have a DNF average of 12.

If you ask for the means and averages which I generated: I just ignore them.

No, it would be a 3:00 single. If he got 3:00, DNS, DNS, then went to another comp and got 3:00, 3:00, DNF, then the middle would be a 3:00 mo3. That's what he was asking.

Since the average is unofficial anyway, it's more like doing getting a 3:00 the one day, then deciding you don't feel like any more attempts that day, and then the next day get a 4:00 and a 5:00. I'd count that as a 4:00 mean of 3.

I just got a LL skip while doing ZZ and phasing. Chances?

Did you mean to use the Probability thread?
But a lot

 

[Sajwo]

So you take all the sub8 results from all the countries and average them (including sub7, sub6 etc). What countries have the best average? I would be very grateful if someone could calculate that

Do you mean all sub 8 averages? Or every sub 8 single?

Singles

Wouldn't this be biased towards countries that have just one really good solver who only goes to a few comps a year so has less chance to screw up?

USA in 8th place. unacceptable. how are we supposed to MAGA under these conditions?

interesting stats tho. nice work, man.

 

[Bubtore]

Has anyone ever done the sum of country ranks, not only using the NR but top3/5/10 instead ?

Has anyone ever done the sum of country ranks, not only using the NR but top3/5/10 instead ?

Which sum of country ranks? There's a few like list of countries, or list of people from one country.

 

[Bubtore]

Like that :
https://cubingchina.com/results/statistics/sum-of-country-ranks?type=single
or the KinchRank :
http://wcadb.net/ckinchranks.php

But using the top3 competitors from that country and not only the NR holder.

What's the most someone's improved between competitions?

Could someone compile a list of ID with no members? Probably need to spoiler it though.
