simple SSCAIT rating statistics

I pulled down a rating table from today and calculated a few simple statistics.

countmean elomedian elo
terran2419651884
protoss1820072050
zerg1620132017
random419011909

1. Terran is the most popular.

2. The fact that the mean is higher than the median for terran implies that a few terran bots stand out (like #1 Iron and #2 Krasi0), but most terran bots are weaker. Terran seems more difficult than protoss or zerg.

3. The higher median for protoss over zerg suggests that protoss may be easier to get strong with (contrary to my opinion).

4. Random struggles, as you might expect, but still has a higher median elo than terran.

If you look over the colors on the rating table, you’ll see that terran bunches up toward the bottom and zerg bunches more toward the middle, while protoss is spread throughout. In the upper part of the table, protoss and zerg seem pretty equally represented, though. There is not much difference between them.

Also, 62 bots is a lot!

Just another one of the "told-you-so" opinions, but I've long been claiming (maybe since 2010) that Terran is the hardest race to program a good bot in, but then follow the other developers' replies: Siege tanks OP, Vultures OP, Goliaths OP, M&Ms OP, etc. ==> Terran OP. It's only when you feel the struggle to program a Terran bot for a few months yourself, you *get* it. Of course, it appears quite easy from the sideline when you watch IronBot kicking butt left and right. :)

OTOH, Protoss seems to me to be the most straightforward and easiest to get satisfactory results in bot vs bot matches early on. But at one stage of the whole endeavour (probably at around ~2100 "modern" ELO rating) you hit something like a glass ceiling and it's only getting exponentially harder from there. TscmooP and Bereaver are the most notable exceptions in that regard.

Still, I think sky is the limit for Terran and especially for Zerg. Perfect micro pays off tons for the latter as evident by Tscmoo Z' queens & defilers play.
