I've shot that way in the past, no matter what poundage I shot, I'd release just short of anchor. it played on my head for awhile, even though I was very accurate. My brain just kept telling me when to release. After awhile, I came to the conclusion, it works, so go with it.
for some reason, the last 2 yrs or so, I draw right to anchor, but release as soon as i get there. It feels right, and it works for me.
