You got it spot on with the grading system analolgy.

Giving more claps for pieces you loved and less for the pieces that you found just Ok is the best strategy.

The number of fans a piece gets doesn’t matter too much, it’s the claps and interaction a piece receives that contribute towards its earnings.

If you’re consistent with your clapping strategy then the lives you enjoy will earn more from you than the ones you are less fond of — measure by way of claps.

I understand that it can sound pretty confusing, but once you get your head around it then the clapping system seems to be a pretty good one, in my opinion.
