I know this is an old thread, but I was just kinda jumping around, and read your post about KO's not working when the body starts to charge up on adrenaline. I had an argument with a buddy of mine, more of an aquaintence, anyway we both trained in Juko Ryu Jujutsu for a few years, and 3 of our guys went to a Dillman seminar, and came back all geeked up that they couldn't get knocked out by pressure points, they all admited that they felt something, but never lost there balance, or staggered once. they kept saying it was mainly because of the fact we take so many Ki shots to the body that our bodies and minds were conditioned to deflect the PP strikes, I argued that it was our bodies getting an adrenaline dump, that probably insulated our wiring against an attack in this manner... thanks for kind of resolving this in my eyes at least...
