We covered all official games since the release of SC2 (means no beta games) and for big tourneys (256,512 or 1024 cups) we included only the games from the quarterfinals on:
Terran 56.08% 369 289
Protoss 50.89% 286 276
Zerg 39.18% 163 253
Note: The system counts every single map in the games of our Matchticker without mirror matches.
The Map stats might be interesting too but we need more data for that imo. This whole page will get really interesting in a couple of years to see which race had the upperhand over all the patches that will come up in the long run.
We will also add stats broken down into the 3 matchups + seperate stats for each patch that is still to come!
PS: I'm looking for more people for my staff to help out with the matchticker data so we can deliver good statistics. We are covering all the european stuff already but i'd like to get some american people (it sucks to ticker games at 4am in the morning^^) and especially some asian in which a good knowledge of asian tourneys, leagues and cups. Let me know if you are interested or know somebody who might be Thanks!
