I've used those kind of methods too but specifically watching an
interpolation patch,
What about these cases:
1) it falls from 1 to zero because it's looping not mirror looping
(you rule out large jumps I know ;-) );
2) other start and end values that make ruling out loop-case more
difficult;
3) a Custom Curve that wobbles (it's derivative goes +ve and -ve a few
times in one cycle). I was looking at some Actionscript interpolation
functions the other day (Robert Penner tweening) and there were a
couple that were complex functions that did overshoot then return to
end value and wobble-up-and-down to end value.

This is how I'd handle it. It simply detects when the output starts
to fall, so it'll happily work with either loop or mirrored loop,
and most curves / tension settings. It'll detect when any value goes
from rising/stable to falling, so you can use it elsewhere too (I
tend to use other methods in place of interpolation, at that point
there's no guarantee you're going to have a convenient way of
determining state based on time).

Use the Tolerance control on the Conditional method that I
suggested. I think it was included for a reason ;)

The easyest way i can think of doing this would be to use a square
wave LFO alongside the interpolation patch. That will basically give
you the phase port you describe. Add a watcher after that and you
have your bounce pulses.
