Just did another Prov watcher, and here's the parse result with my acc on it. Note that I still don't have optimal melee set, the only acc swap I had is Ziel charm, everything else is avg joe Oce head NQ and Thaumas 4/5.

You can comepare my acc with some of the higher acc DD job such as DRG, rag DRK and WAR etc. A lv 99 Rag DRK and WAR (which are some of the highest acc DD in this game atm as long as they pop JA, due to +40 acc on rag) only have 90%~91% hitrate. DRG, another high acc DD job is only 86%. I'm 84%, only 2% behind DRG and 7% behind rag 99 DRK, without Khepri head and Letalis mantle. With K.head and L.mantle, which is another +28 acc, my hit rate would be capped.
(speaking of which, should have used double mad on dragon since nobody caps acc with just 1 mad D; )
I'd go out and assume, anything a WAR and DRK can hit with a normal TP set, a dagger COR with proper set can hit it with hunters too. So if your melee DD can hit other VW without acc song, no way COR can't hit it either.
