[ot][spam][crazy] Inhibition Efforts: High-Precision

[Undiscussed Horrific Abuse, One Victim of Many]

yay, battery averages!

I thought about just averaging the values, and I was like "why wasn't
i considering this", but when thinking about it I'd rather do a linear
or stepwise interpolation, so that times when the values can be polled
faster or slower don't impact it as much. This seems to make sense for
battery charge, which is not expected to spike. I'm not sure how it
works out for current, if there are spikes.

Seems like either way it's a fudge, and you'd want to run the process
at realtime priority or something. I dunno.
