When I'm going through the widget list (glances), all the widgets show their names except the VO2 Max widget.
Stress
Heart Rate
HRV Status
Body battery
Sleep
Good <-- this should be "VO2 Max" right?
Calories

"Good" is the VO2 Max value and the glance is called Performance - you're right. I saw the VO2 Max chart there and I wasn't looking for the right widget name, but the point is to unify it and use a static name so that the widget can be identified by the name and not just by the icon like the others.
So this could be called Performance or better "Performance: Good".
