No bunched up panties here. There are no free lunches, more than spec speed in a spec length barrel of 26" leads to higher than spec pressure. How do you account for the higher than spec speed without higher pressure? It is a very good bet that if spec velocity is reached with less powder than a Manuel lists that spec pressure has been reached in that particular rifle. It really is that simple.
A 10% increase in case capacity will yield a 2 1/2% increase in velocity at the same pressure.
