I think we are on the same page, I wasn't disagreeing with what Drew said. He mentioned "braking while up and down and throwing the bike to full lean immediately at turn in" to me that was like saying get to the slowest part of the corner (which I would think is when you are at max lean) quickly from being up and down, thus squaring off the corner and then once you've apex'd start thinking about standing the bike back up and getting on the gas.
Quickest to the slowest point and quickest away from the slowest point. Hopefully he chimes back in to confirm or deny if we are thinking of the same idea.
