The side split equates to a 5 percent #s advantage for the Axis (52.5-47.5) its something we aim for, but as you all know, FSO attendance #s cannot be strictly controlled, so dont worry about it. Its a "target" for side #s, thats all.
50/50 splits are the most common, look at the logs and see how many frames there were with exactly the same #s on both sides, with close to 500 players committed.
