Riding with one foot - need help

I have read the help file on learning to ride with one foot. I can idle with one
foot and I am trying to rock over the top and forward. I can get the pedal over
the top but when the pedal continues on around the unicycle goes out from under
me in front. I can do this pretty consistently. What do I need to do to get my
body to continue on forward past this vertical point along with the wheel?
