AeroPod, PowerPod and Newton

Hi, i've just bought a new Powerpod, and i'm having a hard time finding a good strech of road to do the O&B calibration.

It's a very windy season here, and i think constant gusts are keeping me from achieving best results. Any suggestions?

I've uploaded a calibration ride for analysis.

Thanks in advance.

Added a longer subsequent ride for further data.
