I'm pretty sure it's all in your head. I've never seen this happen before, and I've been playing this game for a while. There is absolutely NO WAY your players earn between 700%-900% Skill Gain after a Game if your Team Intensity is set to Hard. After a Match, YOUR WHOLE TEAM earns a collective amount of Skill Points that come to about 7-9, but each player doesn't get 7-9 Skill Points.
