The phenomenon that you're describing with the increased wear rate of your pad in this example is likely due to the pad having very non-linear wear versus temperature characteristics - in which the peaks of energy input at peak deceleration causes accelerated pad wear. Have you guys done a brake dyno test regarding wear at different temperatures like that described in SAE J2707? That will likely confirm that hypothesis.

Sure, if you ignore all the chemistry involved. If it were as simple as the bolded, then there would be very little variety to brake pads. Because of the chemistry involved, is where all the different brake characteristics come from.
Likewise, different whiskeys wouldn't exist because it's ultimately "just distilled spirits", ignoring all the nuances.
If only it were that simple.
