Head or tail wind?

Hello,

I usually do round trips, resulting head and tail wind (I can feel that in the legs). The resulting Powerpod readings in the Newton software indicates always tailwinds (at least I think that the blue area indicates tailwind).

Perhapse that explanes the poor powerreadings (I think/hope I 'm in a beter shape)

I included a few rides to check.

I had same issue and very low power values on descents.

Check the Wind Scaling value in the Profile. There is a bug in ISAAC which sets it to 1.000 by default when you create a new profile.
This is far too low and should be either 1.4 for handle bar mount PP and 1.7 (I use 1.65) for Combo mount.

I have already changed that setting to 1,4 (I have a handlebar mount). I also adjusted the CdA to 0,4.
