As soon as you move out of the heat range of a pad, it will either fade, wear rapidly, or even crumble like you described. I'm sure any top tier race pad will fare better. And ducting will certainly help
Did your rotors get any surface cracking? If not, you've probably got a lot more thermal capacity left to take advantage of a hotter pad
Good point. Yes, the full race pads have a higher MOT than endurance pads like the RS19s. No cracking, so the pads and cooling seem to be the limiting case indeed.
