OK, BB, now my head hurts. Cut that out!
Seriously, why would you want reload rates in fractions? You'd want reload rates in multiples. After all, if there are 10 impulses in what now constitutes a turn, a CSM has a 30 impulse reload rate. APB has a reload rate of 10 impulses. Surely you don't want to have
anything with a reload rate of 1 impulse!!!
