FW5 upgrade: watts are now higher than previously

[stefun]

Hello
I've just load FW 5.13 into my newton+.
I tested it on two rides power numbers are different from rides performed before I upgrade my newton. Because I'm curious about things are working, I'm always riding with newton and a powertap hub.
I observed that on the two last rides realised with the new FW5, power numbers approximately are 6-7% higher than previously.
Previous cal ride carried out in februar 2016 is always running in my newton. However I suspect that the autocalibration feature changed how things are computed by the newton.
The two first attachments are ride performed with the FW5 upgrade.
The last attachment is a ride performed before the upgrade.
Finally I join the profile extracted from the newton

and the profile into my newton:

What could I need to do?

1) Reload the profile performed with a cal ride (without wind, on an almost flat, almost smooth road), fine tuned with against a well calibrated PT DFPM.
2) Make a new cal ride?
3) Allowing the device to do an autocalibration by itself and fine tunning this auto calibration with the profile uploaded here?

Thanks for your help.

What's happening is that FW 513 does a better job of measuring Crr, so your default value needs to be adjusted a bit, to 0.004 (typical for a good road bike).

Modified profile is attached.

Many Thanks John
I will try this profile sunday.
