And I agree. I’d much rather have it underestimate than overestimate when it comes to training runs.

I've also noticed that RunKeeper doesn't do polling intervals that are as granular as my Garmin GPS [Forerunner 301]. In a way, this is actually nice, because Garmin can overestimate distance due the extra jaggedness in the course tracking. My impression is that RunKeeper may slightly underestimate distance. For training purposes, I prefer the underestimation of performance. I’ve lost GPS signal without notice in very odd places with RunKeeper, so I went back to my Garmin pretty quickly.
