Cycling Power Estimator

I should maybe raise the average window from 3 to 10s, to smooth that grade variation (especially in descents).
My guess is that 0 is probably closer to the real value than 450W (at + 5/7% grade, I am between 200 and 350W). I agree, you probably won’t get heuristics that works in all cases. -
@bubuche Check with the latest update, I’ve re-done the logic.
Now if there is no cadence sensor, power is always computed on the difference between actual speed and terminal velocity.
Terminal velocity is still subject to grade smoothing. The altimeter looks at altitude in 20cm chunks apparently, so you need several metres to compute a useful grade reliably.This is computationally more expensive but may not make much difference overall.
I’m just hoping for no unexpected regressions. -
@mickywickyftw thanks for the update, I’ll try this week hopefully (on the same road, to compare).
One suggestion could be to wait for a few more seconds when the slope reduces before using standard formula (I totally ignore if there are mathematics models behind this, just intuition and probably hard to calibrate). I mean we are still fast for a while when the grade drops from -4% to -2% for example.
