Calibration check and a question

[orhch]

Hi,

I am on my second PP unit (the first got replaced due to a problem with the wind port).
I completed the O&B calibration ride and it will be great if you can verify if everything is fine with it.
Attached are the calibration ride, the ride I did after it and the profile that was generated.

I think the wattage in the ride file could be on the lower side, but since I don't have something to compare it to, this is only a speculation.
I noticed that in the calibration of my first PP the "Aero" value is 0.736 and now with the new PP after the calibration the value is 0.356. In both cases I rode on the hoods.
It is true that I changed my stem with a shorter one between the PP exchange, but does this change in the value make sense?
I don't think I got more aero with the new stem, but this is again subjective.
Also the friction value went from 11.376 (in the old PP) to 8.693 (with the new one)

Thanks for your time!

Here is the profile from the first PP (before the unit defected) if you want to check it.
Same bike, same tires, only the stem is different now (shorter)

Your ride file looks perfect.

Thanks John!

Is there a help documentation where I can read more about the questions I have about the "Aero" and "Friction" values?

Aero and fric are internal factors that date back to the original iBike. We should probably delete references to them...

There is a brief description of them in pages 27-29 of Isaac instructions.
