i think the draw stays close to the same when i scrunch due to over alignment, in photo two the line acros the shoulders croses the line of the arrow, which is not the case in photo 1.
im in the process of building up to the weight, it is a 5lb jump from my last,
if i practice right i can keep form from photo 1 every shot, that is one arrow at a time, if i shoot 5 or 6 in a row i will scrunch by the last couple arrows, in the last day or two with photo 1 form i havnt missed a tenis ball out to 20 yards. i can get 20-30 shots a session that way then i start to get tired and form falls apart, i have been improving because i can make myself take a few hour break.
