Hey Whoop. I’ve had two runs that had zone 5 intervals in them and both times I felt 5.0 detected too low a heartrate. I unfortunately did not wear a chest strap but a Garmin Watch which previously was quite in line with the Whoop. While Garmin goes up to my max hr of over 200 (which is also my perceived exertion), Whoop stopped at 193 this time, and 185 (which isn’t even zone 5 anymore) last time.
Anyone else having these issues? Is this something than can/will be fixed with firmware updates? If I remember correctly the 4.0 had similar problems when it came out.

There’s been a lot of problems with whoop MG it seems like. But make sure if you’re wearing it on your wrist that it’s not flying around because if you move it around a lot it will cause the HR to be messed up.
