Version 3.54.4.2 focuses on VO2 max, altitude stability, Zepp Flow, map navigation and golf behaviour. The most interesting item is the VO2 max algorithm change. Zepp Health says the update improves VO2 max accuracy, but also adds that results will be gradually calibrated based on new workout data after installation.
