The idea being that if the capacitor is not fully dumped, it will sooner
float to full charge and you need less time to measure how long that
it takes to be recharged:

Whether this might work depends on how long the hardware takes to do a
full capacitor dump. If it's FAST, this approach won't work. If it's
SLOW, and the above code only does a **partial** capacitor dump, the
following should work well:

Exactly. Again, I haven't tried it, and it will certainly NOT work on an
emulator, but it's worth checking out.
If nobody posts results on this today, I'll hack something together over
the weekend and post a good set of paddle reading routines with dejittering
and HOPEFULLY (fingers crossed!) not requiring display time.
