The reason I think this is valid is because there seem to be changes with recent battery models. I know my pack can produce a max of 500kW as measured by myself and
@ShotgunF15E. There are others who have measured their packs at over 500kW as well as under 500kW. As we discover other packs out there I suspect that we will see even more power variations. We also know that putting a more powerful pack in an older P90DL will yield the expected higher output. Given these factors, I think it's better to track by battery rather than by car.
