Uh, so there are two rolls per enemy. The first roll encounters DAR. Which as already stated, is the rate at which a monster drops anything for you. However, the other side of that is RDR (Rare Drop Rate). Should a monster pass the DAR and fail RDR, you'll just get whatever drops. If you pass both DAR and RDR, you get whatever rare item that enemy gives. The drop table rates are not what you get given an enemy drops something. The rate you see on that table is the calculation of DAR x RDR. Noting which enemies have higher DAR rates for given hunts can help you as opposed to similar rates on another enemy that may appear the same but has a terrible DAR and sucks to hunt from without boosts.
