A few random thoughts
IMV A lot of thought was put into wing chun by our ancestors. It seems to me that certain trade offs were made between, on the one hand, power and, on the other, positioning. Wing chuns body positioning and structure (i.e. upright, square on with elbows in and forward at close range to the opponent) is such as to allow for quick recovery when an attack misses or is deflected. Thus the the time it takes to establish a new line of attack when the old one is lost is kept to a minimum. In fact i'd go so far to say that wing chun, by virtue of its very design, recovers faster from a thwarted attack than any other striking art. This is what gives wing chun when done properly its relentless, always one step ahead, strategic quality. They may stop the first one but in doing so they will expose themselves elsewhere (like sending all your men to one end of the castle wall to fend off attackers while another party sneak around the other side).
Of course more power can be generated in a punch by really pulling the fist back, throwing all your weight behind it and charging forward ( a la the haymaker beloved of bar room brawlers and street thugs the world over) but this is easy to detect and thus avoid and leaves the executor in a vulnerable position if it misses.
The question then becomes how to maximise ones power within the biomechanical parameters that the system places on you (or rather that you have set for yourself since you have elected to do it). This is the origin of 'inch' force and the question of how best to cultivate it. I will try and post how I think this is achieved when i have more time.
