I don’t know what you mean (because I don’t use wearables).
The points you earn for e.g. an Aphrodite (500 for the workout itself, 80 for a star, 100 for a PB) are not related to anything else.
I don’t find the thread or post but either @Charly or @Ben explained that in case of the Apple Watch (and I expect nothing different in case of Android wearables) the calorie consumption was more or less a guess done by Apple.
Edit: got it!
