I've got Statmasta, but I think I messed up that one square...
3 games... Grrr...
Right, I'm suggesting that you download it again and copy that square over to your current sheet.
3 games are a bare minimum to get some sort of an average between "lucky wins" "random losses" and normal matches vs each FG.
The trainer can be used for FGs that aren't affected by any patch changes since the patch number shown in the trainer, though.
Hope that helps, and good luck!
