With the idea of sliding comparison, you might transform this data to look
at absolute magnitude of change over time, and normalise it.  Reviewing and
comparing the streams as a visual graph would help inform whether or not
they are then automatically correlatable.

So, you'd make a calibration test function that produces short bursts of
graphable data around instigating motion.

Then you'd make the calibration function itself, but you'd keep the test
function so that people could use it to troubleshoot issues they run it.
