Variation of data

Hello

When I compare the data with my DFPM (I carry the two on the bike) with the Powerpod the standardized power is practically the same, there is very little difference but the average power is much difference. This difference becomes even bigger when there is drafting.

It has a solution?

Thanks

Please post a .ibr ride file, along with the associated .tcx file from your DFPM, and we will take a look.

I used the "File/Merge Files" command to add your GPS data to your ride file.

I don't see any issue in your ride file. Your two PMs measured within 1W for the ride, and in any given section, they are within a few watts.

You have a drafting section between 1:19 and 1:35; in that section the two PMs are within 0.1W of each other.

The only place where there is a big difference is at the 2:17 to 2:19 point, where your PP overshoots watts. However, this was on a downhill; most likely, you were in a tuck in that place.

I think you are OK.
