Kurt Kinetic Power Curve

This data was gathered using a Garmin Edge 500 and my prototype L/R measuring Power Meter which is still being worked on. The latest upgrade to my prototype power meter is here

Power versus Mph.
Blue dots are actual test points, the black is the 3rd order polynomial fit, and the red is the Kurt Kinetic regression they provide here.

Now in a semi sensible unit (power and km/hr)
When you accelerate the regression curve can’t capture the extra torque, and thus extra power. This is the same problem in coast down. Stored energy in the flywheel is released but you aren’t putting in extra power. I’ll add to this over time, but for now, Kurt Kinetic Road Machine = solid investment!
