lets do some math! seat height from BB to seat based on lemond method is 30.5 inches. bike A has toe clips, platform pedals and uses soccer shoes. bike B uses spd sl pedals which are 1/2 lower then bicycle A's platforms, AND the sole of the shimano bicycle shoes is apx 1/2". the soccer shoes are apx 1" high. confused yet? so, by my approximation, bicycle B should have the seat lowered 1 inch to match the overall seat to pedal connection of bicycle A. does this make sense?
