May not really be target panic. If you are not overbowed, you may be reverting to wheel bow habits. Since a compound lets off, it takes less muscle force to hold the bow, so we tend to relax at the back. With a traditional bow, when you stop pulling you will start shaking. Try not to pause too long at your anchor. Don't release from your anchor point, use it as the starting spot for pulling through. Now if I can just remember all this next time.............
If this problem continues, you will develop target panic (really the uncertainty caused by the fear of missing). I had to overcome a very similar problem several years back and it is no fun if it gets to the Target Panic stage.
