Too high watts during windy days

I am still learning how to train with Watts. PowerPod is great and I like it.
I am on camp on Mallorca and since three days I am experiencing too high watts measurement. I did calibration every morning as I detach PowerPod every day. The only difference I see is high wind for these days.

Is there any general recommendation how to calibrate PowerPod for correct measurement during windy days? We have wind about 20km/hour and more.

From my Garmin I can see ride of 108km ride 4hours with average speed of 27.2/hour and average power: 493W Max power 3430W and Max average 20 minutes power: 823W.

Please post your .ibr ride file.

Also, please do a short solo ride, where you ride down the road five minutes, then turn around and ride back to the same starting point. Please post this .ibr ride file too.

Finally, please post an image of how you have your PowerPod attached to your bike.

Actually, your problem is pretty simple.

Somehow your PowerPod profile was changed so that the wind scaling factor was moved from the factory value of 1.6 (combo mount) to 4.6. This will cause wind and watts to be crazy-high.

I fixed your ride file and corrected your profile, both attached.

Load the corrected profile into your PowerPod and all should be well.
