IIRC last world (at least in the beginning), Perception and bow/arrow quality all increased the damage (on top of the base damage of the bow and stone/bone arrows you're using), and marksmanship determined the speed the aim bar increased (and as a full aim bar does also increase damage, marksmanship would indirectly affect damage).
Archery has been heavily nerfed since then, and although marksmanship seems to have the same effect I'm not entirely sure what everything else does but wouldn't be surprised if it was just functioning about the same but the numbers were decreased (and blocks now reduce arrow damage too)
