They aren't effin' doing the same work. Muscles have their sweet spot of extension where they can put in the most power. That better match with the power stroke of the crank revolution. Just do three squats and you'll see.
If you add 10% to your properly measured saddle height, your feet won't reach the pedal at all, so that's bull****. And anyway, "properly measured" means "ideal". If you change from that in either direction, you're kicking yourself in the arse.
