AeroPod, PowerPod and Newton

Hello to all
I made a 20' test on a out and back ride. attached the file of the ride.
After the training I made a "calibration check" with Isaac and I had a sensible modifcation of the avg Watt and Aero value.
In detail:
Areo from 0.607 to 0.638
Avg Watt from 309 to 270 W

Just before the test I made a cal ride. I do not know if the cal ride was automatically loaded in the profile. But this cal ride has an aero value 0.607 which is lower compared to previous cal ride (value of previous cal ride was 0.648). Attached the cal ride made just before the test.

Is there any mistake?
Wich is correct power value to be considered?

Thank you for your help
Stefano

Please post the FTP ride file. You posted the calibration file only.

Here attached the file "Test 20' 6 dic 2016 - Flat ok.ibr"
This is the ride with 20' test to find the FTP. It was attached also to my previous message (if not, sorry).
Thank you
Stefano

NICE FTP!!!

Your ride file is perfect and so is your calibration.

FTP = .95 x 309 = 294W

Ok thank you very much for your check.
