Nope, energy change has nothing to do with this. It's a function of vehicle starting velocity, ending velocity, vehicle mass, and time. The shape of the energy flux into the pad is affected by friction changes (like you're mentioning), but the overall energy absorption for the pad is a function of the vehicle parameters mentioned above. 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.
