dmalvarado, Even if sitting and riding one legged to practice pedaling circles, the upstroke is only really powering from 6 o'clock to 9-10 o'clock with very little power after that. There are a confusing number of ways to look at pulling up, but the "scraping mud off of your shoe" is the closest to how I pedal.

When standing there's just less of the pull stroke, perhaps just enough to help the leg that's about to go into it's downstroke.
