Heartrate zones using the wrong max HR

Bugs and Support
1

I have a max HR of 173, visible in my Zwift profile. However, the “Heart Rate Distribution” graph shown in my Android companion app after an event appears to be using a max HR of 200, as shown in the attached image. That incorrect max HR then leads to incorrect Z1 - Z5 zones. Is this a bug or am I doing something wrong?

Thank you Zwift Rockstars!

I see the same thing, and so do several friends who ride and race @Ride_Cyclery.

Plenty of Feature Requests to customise this are around (this thread references a few). Whichever HR methodology they have based it on, no-one seems happy with it (the people that care, that is). Best to do analysis outside of Zwift imo.
