Since we're talking cornering technique, why not go balls deep?
I get a leg out and half my ass off the seat for most corners. I establish body position before the corner because I don't want to upset the bike mid corner by moving around. The only thing I do to actually initiate the turn is counter steer, so my body is pretty much motionless at the instant. It's the smoothest way I can glide into a corner. Counter steering is my margin of error. If it's a blind decreasing radius turn all I need to do is increase the counter steering input while staying on the throttle...again, my body stays pretty much motionless.
It works.
