Something like 20ft/min or so or (coincidence: that's 3s > per foot) but definitely slower than 30ft or 10m per minute. Which means > our 3s intervals give us 1.5ft or 50cm per interval.

Haha oops. 9 m/s is pretty fast. Replace m/s with m/min and my commit message might make more sense. > > I basically understand what the patch does (duh), but the commit message > makes no sense to me... > > /D >
