RE:10G limit. On races in general or just the Red Bull ones? IIRC the RB ones have always had the limit in place and, if a pilot happens to pull more than the limit, they get a time penalty. Can make for interesting viewing if there is only a few seconds between 1st and second place and the last person up is trying their hardest to move up from 2nd to 1st, whilst doing their best not to get a penalty.
