I'm not sure what you mean by fully committed, but if I go by what Aikido folks usually mean, then yes, it's very possible to strike someone in a way that is not fully committed by that definition with strikes that are very dificult to exit.

BTW, I'm not advocating boxing, and never said that I do - I only brought it up to show how small a percentage of strikes actually connect enough to do any damage, a small enough percentage that focusing on "one strike" is probably not realistic at all.

Best,

Chris
