…and getting testy;
There is total energy, and then there is peak power, time to peak power (which in audio circuitry we referred to as “rise time”) and duration of peak or near peak power. So you’d likely want to be able to graph it as power over time, to “really know” what’s happening. Point being of course that total energy would be somewhat inconsequential unless the power were up to a certain level for a certain period.
But maybe you got it just like that already. If so, carry on. Don’t mind me sitting in the corner and muttering.
