You will probably notice that if you close your eyes, look at something else, watch the tip of your arrow instead of your target, anything else but the target. . there is no TP.
It is typically the combination of you being locked on target, pulling back, and your mind tells you to release. And it also has very little to do with bow weight, in spite of what you hear.
It isn't easy and it takes a long time of rigid practice to get past it if you really had it ingrained. But.... you can do it, generally with help.
