I've got another idea that requires no extra hardware. I think has a
solid theoretical basis which I've explored below in sufficient detail
to raise suspicions that I miss my old line of work:
tl;dr: Record the dt time between button clicks, adding dt to the
accumulator each time by hashing it into the persistent state.
