Have you been able to dial in the trip distance?

I've noticed that the trip on the metro seems pretty accurate despite the jumpy instant speed reading, which means it is getting most/all of the vss pulses anyway.

The cheap fix is to skip the timing of the vss pulses and just compute "instant" speed based on last few seconds worth of pulses instead of the last .5 seconds worth.
