I have the updated version and the Magene is reading 5-10w lower than the Assioma Pedals. They were within a 1-2w previously. I calibrated the Magene prior to my workout last night but didn't calibrate the pedals. Possibly that is impacting the results. I'm planning to ride again today and will compare the fit files later.
SOLVED. So full hand up accountability the reason the power meters were so far apart was on me. So anyone reading this will not succumb to the same fate, I calibrated the PM when it resting on the riser block I use occasionally when I'm Zwifting. The user guide does establish that the bike needs to be level when a the calibration is performed through the app. I think I walked backwards into getting it correct prevoisuly and didn't have the bike attached to the trainer when I calibrated it after I installed the power meter. My guess is there is possibly a gyro that is thrown off when the bike isn't level when it's calibrated but that is simply an educated wish.
