the win lose ratio's from coh2 chart.com

currently the whermacht is falling a bit behind and OKW looks really bad. 1vs1 (ATM could have changed since it a updated stats)
I should make a copy pasta to refute this because this comes up as "evidence" way too frequently.
CoH2 is a game of Axis vs Allies, atleast in ranked play.
Collectively, the allies have 1,410 games played.
Collectively, the axis have 1,205 games played.
This isn't as bad as it was last time I saw it, where Allies had double the amount of games played, but you have to keep something in mind. You should also note that this is a sum of games over the course of the week, but on any given day there is a different amount of games played for each faction. For example on October 31th had MUCH fewer games as Ostheer and Soviets, compared to the other factions. October 30th had a huge spike in US and OKW games.
If we assume that players within Allies top 150 and players in Axis top 150 have an equal chance of playing against similarly skilled players as they do lower skilled players (outside top 150), then Allies having more overall games played should mean that they have played more games against lesser skilled players and thus likely won those games. (And in reality, it could be that US players are playing 80% of their games against lower skilled players while OKW is playing all their games against top 150 players, hence having a win rate closer to 50% which is the ideal based on the MMR.)
The only way this would be relevant is if it limited all games counted to players within the top 150 and any games against players outside that bracket would not be counted, or if it simply included all games/players and not just the top 150.
