Funny how jaedong never thumbed down Polaris Rhapsody as the dual map. | ||

Cause I haven't coded it that way yet, silly! But graphing by time also has its advantages in that you get to see exactly at what times the shifts occur. That itself makes it interesting to look at. I will address some of the other stuff tomorrow, and I guess I could start a thread on some stat theory cause I think that's interesting hehe. But that will have to wait till tomorrow cause I have to translate like 15 pages tonight apparently. | ||

Even if you reject that premise statistics can still reflect map balance - you just need to compare against a baseline that reflects the difference in skill between the three races. The reason WL doesn't make sense is because I am trying to use usage statistics. In regular proleague non-ace matches every time a player is sent out they were specifically chosen for that map, and hence if a map favors a certain race you ought to see that race be sent out more frequently than you would expect if it were perfectly balanced. In winner's league it doesn't say much that crazy-hydra played on circuit breaker if the reason he did that was he happened to win 3 games before that. Maybe you could argue that you could still analyze the first game a player is sent out for but when Jaedong gets sent out in the 4th set that's not because of the map that's because god damnit jaedong oz is down 0-3 again. The same reasoning applies to ace matches in regular proleague - you would expect the correlation between the race that is sent out for an ace match and how good the map is for that race to be lower than non-ace matches. edit: Did I just get trolled? I just spent a lot of time typing out some stuff that I think is pretty obvious. | ||

PvTwinration means Protoss wining against Terran or is it vice-versa? So, the Python's Graph indicates a huge favor for Terrans against Protoss? | ||

That would help to show trends in the matchups at a given time. For instance destination was initially pretty imba for TvZ but sometime between december 2008 and march 2009 it started turning around and zergs began winning more often which eventually brought the MU down to ~55%. If you have questions about how you might go about it you can PM me, I do these sorts of things for a living (though am out sick today!). | ||

If you have questions about how you might go about it you can PM me, I do these sorts of things for a living (though am out sick today!). First derivative of a percent change would be rather misleading, so it's not a very good measure. You can see why cause as the number of games increase the average has less and less variance. I'll probably do a 10 game running average maybe in order to see noticeable trends. I have no idea how to smooth plots though, so I'd be interested in learning how to do that since I have some very interesting plots that I will reveal soon Also if you do this for a living I envy you ;___; hmmm doesn't that mean sort of pull the statistics to extremes? if one map is really imba, then the stats will show it with a huge disparity in win rate, since there's a huge disparity + small sample size. however if a map is balanced, then there will be ~50% win rate + large sample size. so there's an exponential increase in "balance" as w/l stats approach 50%...? so assuming what i just said is true, FS is SUPER DUPER balanced? ^^ It biases statistics, yes. I'm not talking about winrates, of course -- cause again I don't think winrate is an accurate measure of balance ("whatever that means"). There needs to be a good definition of balance before we even start talking about anything. What about an aggregate racial balance chart, so we can see overall map balance over time (or was that already done before)? Will be done, with a lot more, in a future post Winner's league games should be thrown out when considering usage rates for obvious reasons. I would also throw out all ace match games as well; while individual games might support a certain argument (eg KT not sending Flash for an ace match on a map support that being bad for terran) I don't think KT sending Flash or Oz sending Jaedong on a certain map says much about the map's balance. You can also account racial differences inherent in the scene by not just comparing the data to a naive baseline of 50%. The data will actually be more useful not that matches are Bo7 too, which is nice. There are still flaws (eg if a team gets 4-0'd we lose 2 games) but if you are doing a statistics based analysis of map balance I think it is the best approach. Yeah, I think it's also fair to assume it will even out in the long run. I would however have to filter out ace matches. | ||

 who loves LT, 815, Plasma and Monty Hall soo...)About TvP @ Python, we need to remember that these are PROgamer statistics, not D P v D+ T stats (I still hate TvP on Python, so Toss imba yo!) because as has been said low-level Terran versus Low level Protoss is already unfair enough, and Python just makes it harder. | ||
