EPOC on S7 vs S9B

[Egika]

I have done a couple of runs using both watches. S9 with chest strap.
All values like calories, rest time, heart rate, PTE etc. match well.

EPOC does not and is 80% higher, on the S9.
Why that?

It is because FB vo2 max estimation is very bad if you are not a runner and Don’t do a proper vo2 max test on S9, it will output very large epoc value because it thinks you are in worse shape than what you are.

For example if you do a run after a 90km bike ride, s9b will think you are a couch potato. It does not test your vo2 max based on power meter on a bike ride, and it forgets that you had a long activity, it only test your last activity and estimates calorie and epoc based on your last walk/run. For me it goes from good to very poor in a day. When measuing my work output of 1MJ calores should be around 1000-1300 but in my case it said it was over 1800.
