I think there is a fairly easy solution. Up to your accuracy hits count 1-1, after your accuracy hits count 2-1 round down. So say you have an accuracy 7 weapon and you roll 12 hits (it happens trust me) well 7 of those hits count normally, then we are left with 5 hits, then divide by 2; 2.5, round down 2, plus the earlier 7, nine total hits. This seems like it would satisfy everyone. Even if it doesn't I'm implementing it in my games because accuracy kind of sucks.
