With a baro-only altimeter, you're not going to get very good speed and
acceleration data no matter what you do. The baro is noisy enough that I
end up smoothing it a ton before differentiating, which is why the speed
and accel data look like they do. I played with a bunch of different
smoothing amounts, and maybe ended up doing too much. Hrm. I could
probably provide a knob in the 'configure graph' window for how much
smoothing the filtered results got; that might be fun to see.

The altitude data is coming directly from the baro sensor, so it's
solid, I'm afraid. No filtering at all.
