Hmm, I wonder how much thermal-resistive factors would affect this. Y'know,
generally when a circuit is warmer, it's resistance increases, and
subsequently it gets warmer, etc, so depending on how the curves weigh out
(if at all), there might be some hidden power savings in doing calculations
cooler and longer rather than warmer and shorter.

Heat is proportional to power dissipation:

    P = UI

while

    I = U/R

So if R increases, I decreases. But then P decreases too and the IC gets
cooler, hence less resistance. Hmm...
