I’ve recently started using a Favero Assioma Duo power meter with my Kickr Core and using TR Powermatch. In my first workout with this set up and just to ensure everything was consistent, I also had my Garmin 520 Plus recording the data from the Assiomas. Both the Garmin and TR were set to showing 10 second power.
Overall the average and normalised power numbers reported were the same (within less than 1%), however in terms of maximum power there was a big discrepancy of around 20% difference (319w on TR, 397w on the Garmin).
I would have through that as they are both measuring data from the same power meter the data would be identical. Has anyone else experienced discrepancies between TR and Garmins and can anyone shed any light on the reason and what I can do about it? 20% difference just can’t be right.
