There is a difference between offense and defense. If you want to
- kill someone by a punch, your 200 lb force (not efficient) or 100 lb force (efficient) may make difference whether your opponent will be sent to grave yard or hospital.
- deflect a punch, your 100 lb force (not efficient) or 4 oz force (efficient) may make no difference.
Many IMA guys try to avoid talking about "finish moves" and only talk about "defense moves" such as yield, follow, sticky, sink, Sung, ... That sometime cause a lot of misleading.
A simple question to ask may be, "How to use yout internal skill to kill?"
