There is an entire discussion here about pushing up vs. pushing down.

from the data that is available using force instrumented pedals and iEMG, it appears that better cyclists tend to push down more and pull up less, that less good cyclists who push down less and pull up more.

as far as i'm aware the Polar left right balance doesn't *measure* this as you'd need force instrumented pedals to capture such data accurately. Nonetheless, people do change the amount of force that goes to each pedal and this can alter each time you ride. This perhaps one reason why i found the Ergomo i tested to be not very accurate (as it just doubles left power).

where have you been for the other five TdF's ;-)

and other riders who have won 5 TdF or other races may or may not pedal at super high cadences
bike position is something else, and wasn't what any of us were including while talking about pedalling
