Back to a perennial peeve of mine.
I never got this essence of the 28/18 Dragon Palms theory where you only use 30% and hold back 70%.
e.g. When GJ first met GWM and exchanged palms. If GJ followed the essence of the DP, that meant he still held back 70%? If that was true, that 30% already injured GWM. Wouldn't 60 or 100% have broken his bloody arm?
Another one, when H7G did the final Kang Long You Hui against GJ in LOCH, the text description makes it sound more like a 100% strike then something where 70% is held back!
If its just holding back 70% when facing weak arsed opponents, then pffffffttt! Whats the big deal? Any damn lousy martial art can do that!
I think its one of those JY 'things' where over-analysing is pointless because JY himself never planned it out beyond a nice sounding plot point.
