Hello, Just tried with PowerTap P1 + FR935; power was displayed on the Garmin Power Datafield, but nothing on the backward power field...

with the power2max crank it does not work well. Returns exaggerated powers.

The formula used in this data field is extremely simple and I don’t see a possibility for “exaggerated” values. What did you see and what is your reason to think the result was not simply your pedaling technique? Contact me. (That said, spider-based power meters don’t support true left-right balance, so your p2m doesn’t really meet the conditions stated in the app description for this to work as intended.)

excellent idea for immediate feedback on pedal stroke. really helps smooth pedal technique. some of the numbers are maybe a bit small.

fantastic some important data to stay efficent on pedalling. fixed on every page on top.

Very cool idea and interesting to see how much power is lost due to inefficient pedaling! Would be cool to add some sort of colour-coding such as 0-30W = Green, 30-50 = Yellow, 50-70=Pink ... Anyhow a very cool datafield!
