I like that concept of "P" in the "Pendulum Accuracy, part 1" paper.  I
had not seen it described like that before.

Is it accurate to think of P as related to the instantaneous variation in
Q?  In the paper it was notated as deltaE/sigmaE, but isn't that also
deltaE/delta(deltaE) ?  Kind of like the second derivative of energy flow
in the system.
