Did you ever get to do another comparison? I’ve not been able to find a video on it.im concerned as I have just recently got the atom and tested against my P1 dual pedals and the Atom consistently reads about +8% over the pedals at all watts tested so far.
I’m confident as I can be with my P1’s due to having them already tested against a few other PM’s and Wattbike pro’s at my local gym and they were virtually bang on with the data so the Atom is the outlier here.
They were also factory calibrated during a service around a year ago.
I’m not sure how to tackle this going forward with wattbike, maybe just take advantage of my 30 day return window
