You really need to try and explain that. How can the bike change it's geometry just because it's off the ground by a couple of inches? The distance from the saddle to the pedals remains static.
I have found that I work harder in the saddle for longer periods of time without moving or changing positions. It's just grind, grind, grind. Sometimes you have to sit up, or stretch a little while riding just as you would while you are on the road.
