Now I have Epix 2 and 530 - I stopped using 530 to get all the staff from Epix2 like Training readiness and status correctly. Now I'm getting 1040. Should i give it a try to use 1040 for biking not using epix2 at the same time for stress/battery counting? Or again - I will not get consistent information on Body Battery/Training readiness/Stress on my Epix after the ride?
