Requesting a calibration check please. My PP had been working excellently until approx 2 weeks ago when it suddenly stopped/refused to pair with my speed sensor which I subsequently lost that same ride (lol). Received a new speed sensor and therefore had to do a new calibration. Also changed my crappy rear tyre/tube to GP5000s + conti tube during that time.
Checking my power against http://www.wolfgang-menn.de/powerhill.htm, PP seems to overestimate by almost 5-10% whereas previously, values were within 2%.
I've uploaded my most recent (post re-calibration) and a previous ride (where I believe calibration was quite accurate)

Re: Calibration check
Just bumping this.
Additional question - I seem to be riding with a persistent tailwind according to my ride file? Could there be something wrong with the wind scaling?

Re: Calibration check
Sorry, I saw your original post but somehow it got lost...
If you can provide specific places in each of your ride files where you think there is an issue that would be helpful.

Re: Calibration check
I think I may have found my error in using the calculator. In regards to wind analysis for segments in Isaac, do negative values represent an average tailwind? Similarly, positive values represent headwind?
