I guess this is what I get for learning on my own. A couple of weeks ago I actually paid attention to what my wheel was doing when I freemounted. My pedals are at about 9 - 3, and when I jump up, I let off on the pressure a little on the pedal nearest me, so the wheel is rolling forward a tiny bit. Once both feet are on the pedals, I pedal backwards a quarter turn, then ride off. I wonder why.
