Not that many pedal meters do true two sided power. Vector pedals do. Quarq synthesizes 2 sided power from a torque algorithm so its more power for each half of the stroke, but both legs affect each half.
Sounds like you've got a powertap. Not sure if that also synthesizes two sided power now, but I know the older ones don't.
