The 6.0 Club


#21

It has been added, though I don’t see how you expect a loss to bring up the average?


#22

I wasn’t sure if there were any others missing. Also, I think he has matches scheduled this week that might make a difference, so I’ll wait regardless.


#25

You’re looking at the set win %. The 6.0 club has always been based on the game win %.


#26

I think Fivec counts by game winrate, not set winrate. Still, grats on the achievement! :smiley:


#27

I do see how there could be some confusion, however, as I said in the OP that you have to have 100 matches played to be considered. What I meant was games. Even I don’t have 100 matches played!


#28

Where’s game winrate then?


#29

Bottom right corner of the MU chart itself.


#30

I don’t suppose other people will be as excited as me about statistical rigour, but I found it pleasantly surprising that 6.0 and 100 games are nice round numbers that happen to be just sufficient to say that a 6.0 club member’s performance is statistically different from 50-50 odds of winning over the same number of games.

Obviously more games are better, but at least a sample size of 100 games tells us something slightly meaningful. If you want, it would also allow each step of 1.0 above to be a tier level, as 7.0 would also be statistically different from 6.0, etc.

To chip in about better performance measures, I also agree that the last 100 games would be a much more meaningful metric than lifetime performance, since the underlying win rate is more likely to be consistent once a player exits their initial learning period.

Maths
Assumption: Normal approximation to binomial distribution is applicable as we have more than 30 observations (N) and p=0.6 is not close to 1 or 0.

Estimated standard error = sqrt [ p * (1 - p) / N ] = sqrt [ 0.6 * (1 - 0.6) / 100 ] = 0.049

95% confidence interval = [0.6 - 1.96 * 0.049, 0.6 + 1.96 * 0.049] = [0.503 , 0.696]

–> excludes 0.5 (aka 50-50) and 0.7


#31

Has anyone run an ongoing ELO-type calculation on the tournaments matches since 2014?


#32

Nope, but if you want to create something like it, go for it. The data in the spreadsheet is as mineable as I’ve been able to make it.


#33

It has been on my theoretical to do list for a while, as in eventually, when I’ve not got so much stuff to do I’ll get round to it. Obviously that hasn’t happened yet though.

I did do some reading up on different ways to calculate elo and I think it seems like an underlying logistic function would be sensible for yomi, since weaker players can simply win combat and beat a higher ranked opponent. This is what they tend to use in chess official rankings aswell, though they started with a normal distribution when elo was first introduced.


#34

Welp, I went ahead and ran the Elo rankings over all games in the history. I couldn’t figure out an actually useful way to represent the changes over time, but here are the top ten players by average Elo:

deluks917		1647.715506
niijima-san		1646.212821
cpat			1639.649159
raziek			1635.015867
fivec			1629.652394
ntillerman		1618.968151
drnd			1616.286345
jengajam		1612.017653
mastrblastr		1606.954037
madking			1601.987083

EDIT: I believe in showing my work: https://github.com/cpennington/yomi-skill/blob/master/Skill%20Record.ipynb


#35

But that can’t be right… Fivec is not and will never be good.


#36

This is just a humble request. I am ectstatic about the work that you have already done. Is it possible to implement this in mysticjuicer’s spreadsheet, so that we could have a real time elo update? This would be a great tool. Thanks for the great work.


#37

I think it’s not a simple thing to do within the confines of the spreadsheet, but of course it could be wrong.

If I understand it correctly, it would require feeding the results of each tournament into the elo calculator and updating all the rankings of those who participate. It’s the sort of thing that could be done if the JuicerChart™ became a website of its own.

Also super awesome work @vengefulpickle *applause* you are a man who gets things done! Though, the numbers look like they might be quite compressed. Does the algorithm use a grandmaster k-factor (16) or a more dynamic k-factor for regular play (32)? I’d just look, but it’s hard parsing a text representation of an ipython notebook on my phone.


#38

@mysticjuicer hey I noticed I have two names on the results chart, is that easy to fix?


#39

Ah, I was normalizing for case, but not underscores/spacing.


#40

RIP most of that top ten. We’re keeping the game warm for ya, mates.


#41

Yeah, it’s using a k-factor of 32, but the liftetime-average is squashing a lot of that variability.

I fixed a bit of the name normalization issues, and ran some calculations using the most recent Elo for each player. So, here’s are the top 20 players (of all time) (including their most recently played event).

Apparently, I also have the dubious distinction of being the lowest ranked player to have played a tournament game in the last 6 months! So, nowhere to go but up! :smile:


#42

Yeah, that happens sometimes. I try to minimize it as much as possible. I’ve harmonized your results under BD_Corro.
