I've tried on a few occasions to get the stomp test to work and have never had luck. Watched the youtubes and know that I am doing it about right. Tried lots of variations - start stomping as soon as the key is turned, a little after, pump steady, pump really fast, 5 and let go, hold on 5, 5 and then hold on 6, all to no avail. Is the 92 different or will I just get it someday?
