I used to shoot hundreds of arrows a practice session. then one day I started flinching at a shoot. i was getting harassed by a wheelie jerk that ended up with lies on his score card. It broke my rhythm. While trying to fix the flinch, for years, I would shoot hundreds of arrows, if I was lucky I could shoot the last few without flinching. I basically practiced flinching for 290 shots and not flinching for 10 shots. Shooting one arrow while stump shooting got me back in the hunting game, but targets were flinch magnets for me. The flinch got into the hunting shots as well, eventually. So I had to take a rethink on TP, I beat it, finally.
If you shoot one shot and it is good. Congratulate yourself, you have hunting capabilities. If it takes 20 warm up shots, but then you can stack arrows like a machine. You are then a target archer. If you can do both, good for you. I always am a bit more confident if I can get a couple of accurate stump shots off before shooting at game.
