Justo calibration

[wolfgang-henke]

Hi,
I'm having two questions:
1) if I run a Justo trainer calibration at one gear setting, i.e. at a given chain ring/sprocket combination,
will this calibration also valid for other gear settings or would I need to recalibrate for specific
other setting? I'm not switching gears during a workout, but rather for different workouts.
2) I have created a power/time type workout program for my Justo in MyEtraining, for simplicity say
a constant Power of 180W over 15 minutes. However, after running through this workout multiple times
I'm getting average powers in the range of 185-190W (no calibrations in between) in MyeTraining history .
Is that within the accuracy/repro range of Justo, or is there any other explanation.

Maybe these specific questions have been raised before, but I didn't find them in Forum.
Kind regards
Wolfgang
