Farthest from you ( the back of the bow). That is the minimum overall length you want for your shafts so you don’t over draw and trap the arrow point behind the bow. there are other “definitions” but this is the most practical in my opinion.
Bowhunters are wise to add an inch, or even two inches, to that measurement to ensure that in the excitement of the hunt they don’t draw a razor sharp broadhead up against their bow hand. Ouch!:cry:
