I just collected this data for the first time today. My L/R pedal smoothness (PS) was 24%/24% and torque effectiveness (TE) was 74%/76%. Garmin states at the link below that the normal range for PS is 10-40% and TE is 60-100%. Ok, great, I’m in the range. But does that mean I’m average? What is best, at the upper end of these ranges? Or in the middle? Should I be aiming for something? If this is important can someone point me to drills I can do to improve?
High scores in pedal smoothness and torque effectiveness are indicative of “circular” pedaling. If you think that’s important, then do drills to emphasize/train that style. One legged drills, as suggested, are a good way to see how high you can get; but even then, over 40% PS is pretty tough to get to.
Probably a more useful thing to do is to train to maximize your power output, and use trends in PS/TE as indicators of fatigue.
