Assuming your right handed left would indicate a weak spine so you could reduce point weight, increase brace height, or I believe you could move your rest out. Not sure on the rest movement as I've never shot off a rest but a bow cut short of center requires a slightly lower spine so it would seem to me that moving your rest out a little would help. If your arrows are grouping together it sounds like your very close to the right spine and probally need only a snmall adjustment.
good luck
