This is a heat issue at the core, plain and simple, The clutch system is getting so hot that it boils the fluid on the clutch end of the system before the brake end. So in therory the clutch is running hotter than the brakes. The crazy thing is, I changed the fluid the day before my pedal went to the floor, so it had zero moisture, possibly air but I doubt it since the clutch actuation felt the same as before.
So where is that heat from? This is why I think it is slippage and heat stacking over long periods seen on the road course. As far as slipping, Im not speaking that the clutch is continuously slipping but rather torque loading, such as down shifts, throttle spikes, heck even if it was minutely slipping it wouldn't always be felt or shown on a gauge but it would be putting massive amounts of heat in the system. I believe this is the direct link to the release bearing support failures and the subsequent destruction of slaves and release bearings.
Maybe upgrading the bearing support will fix bearing and slave failure but it won't stop fluid boil.

In regards to your theory and testing it, do you think that had our cars come with a rev-match feature, these failures would have been significantly reduced then?
