GEE!!

If dV/dt = 0 then I must have maximum voltage. This has meaning.

Hmmm ... if dP/dt = 0 then I must have maximum 'PEAK' power. This might
have meaning IF I splatter all over the band. But for SWR purposes it
means nothing ... I think ... am I confused?

Yes, it is a spot frozen in time, a snapshot of slope at one instant.

What really interests us is average power over a half cycle or more, not
instantaneous power, energy`s rate of change, or power`s rate of change.
