you still didn't get it. I never said you can't yank a pedal at a mere 75rpm, or that 75rpm is fast, I said was once you exceed about 75rpm you cannot any longer pull up the pedal with any useable power and that the most you could hope for was to dead weight the pedal. Then I provided a web link for your further understanding as to what I was trying to convey. If you can't understand me, did you at least read the site from a more professional writer then I?
