Don't know where you live, but those are all pretty consistent within my circle. Advanced wing chun uses punches very selectively as well. I never punch unless to the lower abdomen but those less lethal strikes are usually a waste of time. I have gravel and stone punching bags that teach the new guys real quickly the drawbacks of punches. Thats what happens when you punch someones skull-you break your hand. Perfect technique can only save your wrists the fragile hand bones are not suitable for that kind of impact. Punching is only popular because of gloves, unless you want to do years of knuckle and hand hardening techniques, retire with arthritis and never play a musical instrument.
