Sounds to me that your form of TP IS NOT full blown YET.
Without seeing you actually shoot it's very hard for me to say how bad it is.
Actually sounds as if you have a punching problem. You draw your bow and when the pin gets anywhere near your spot you hit the trigger............Does that sound like what your doing????? Or are you simply just freezing up a little low/high,left/right of the target????
Actually you may want to spend less time shooting.My case of TP began by shooting too much.I would shoot and shoot until I was tired which in turn created terrible habits in my form.Think of it this way....Would you rather shoot 25 quality shots or 75 so so shots? Remember 1 at a time!
Spend some time at the blank bale.Take your time.
