Another thing to consider is that, if you don't lag much, Rapid Fire won't "waste" bullets. For example, if a monster has 10k HP, and you do ~4k each hit with Triple Fire, you'd be wasting two bullets on the final kill shot. Those bullets could be better spent damaging another monster instead of on dead air. Whereas Rapid Fire does ~2k each bullet, less of them are used shooting dead monsters. You would have a greater experimental DPS to theoretical DPS ratio. Overall bullet efficiency though is a problem with using Rapid Fire.
