well if you hit an anchor and pull through as if you were snap shooting,, it may give you more consistancy,,
I can shoot well with no anchor, alot of my bows are short or short draw,, 20 to 25 inches,,
it takes practice to shoot these, that is the key,, practice, accuracy with no anchor is obtainable,,
but you may have to limit your shots say to 10 yards on game to start with,, my favorite hunting bow of all time was 25 inch draw, no anchor, I was accurate to 30 yard groups with it,, and killed deer with it but under 20( some less than 10 yards,), maybe one just a little over 20,,,, I dry fired it and it broke in two pieces,,
when I shoot with no anchor,, I draw the bow as if I am going to hit anchor,, having my elbow coming back into line,, but just release before I get to an anchor,,
I will put a piece of tape on the arrow so I am drawing it to the same lenghth each shot,, that will help your consistancy,,
soon your body will feel when to release based more on the weight of the bow ,, than how far you draw,,
if you are pulling though the shot at that point, the arrow should go pretty much where you are looking,,
the lighter bow is harder to release smoothly,, the heavier bow will pull from your fingers as you get to full draw a little smoother,,
