I'm using made up numbers to explain the logic. The numbers of games varies wildly day to day due to the small sample size. December 6th OKW played 200 games and Brits only played 30 for example. 30 games isn't even enough to have a decent statistical representation of british players in the top 150.
I also fucking hate the new OKW design and have been quite vocal about that, so don't accuse me of bias. I play everything pretty equally. I said the exact same thing when allies Op was all the rage.
You didn't have to make up the numbers, they were there and don't support what you were trying to say.
It looks like you used the 4v4 numbers for December 6 so I'll use those. The numbers of games played were: OKW 216, OST 133, SOV 144, USF 94 and UKF 30. That's 349 axis to 268 allied.
If you assume that the game is balanced, then the top 150 should more or less split the 268 games. Assume then that the other 81 games were all won by the "better" axis players. That would have the axis wining 215 games of the 349 that they play, for a wining percentage of 62%. Instead, the percentage was around 89%.
I'm not trying to make this personal and don't know you or anything about you.
