If you like objective data why would you use random 4v4 to get an accurate data set. Even legends said that the data was flawed because the top players won no matter if they played axis or allies randos, they just played more axis. I just hosted a 4v4AT tourney of elite teams. Allies won every game by 400+ vps, no games we're even close.
If you are using those charts for anything but 1v1 the data will be flawed.
Forgive me if im wrong but hasnt there been balance patches since your tourney plus the vet fix? If there has your tourney results dont mean much now.
