I use my power meter pedals (assioma) for primary power source, but wanted to compare it with the trainer power meter values (as described in the link https://help.trainingpeaks.com/hc/en-us/articles/31340616175373-TrainingPeaks-Virtual-FIT-Files-Dual-Recording ).
While I see different values during my workout on screen, the fit file does show perfect alignment (can't attach example, only screenshot from dualrecording.com).
Love the product !
