When you draw your nock is being pinched and that is what is causeing the jump during the draw. The only time I see this problem is with Beginning Traditional archers twisting the string and bad form.So being that your not shooting traditional, the Nock is too tight causing the arrow to jump off the rest. It's Deffinatly not your drop away rest. The whisker biscuit will help with one problem but not another. Your probably not shooting as accuratly as you could be shooting because on release your arrow will still be pinched at one point or another. My suggestion is to invest in a loop or nocking device and have it installed at the proshop where you pick it up. Hope this helps out.

Here is a link to show you what I mean.
