Hi,
I believe only Edge 1040 has comparable functionality to Epix (e.g. Stamina). Other models like 1030/830/530 are more on "Fenix 6 level". Thus the question, whether using Edge 530 to record bike trainings does affect (negatively) some Epix statistics? I have Physio TrueUp on, so I can see it synchronizes in training load or recovery hours and affects e.g. Training Readiness as well...
