Fenix 7sSS Body Battery after Recent Update

Is anyone else's Fenix 7's Body Battery widely generous after the update? Not sure if it's related to the sleep update, but I've had a couple of nights of crap sleep (sleep score avg of 50-60s) but my Body Battery is up to 80-90s the morning after. It's not accurate at all after the update. Did Garmin change the way Body Battery is calculated?
