The Point Tree shows how your team and your opponent are earning points. It's important to know if you're winning the serve-receive battle because the first ball contact will determine the quality of the next play.
This match started out well in G1. Look at the Pass line where our side passes much better and the kill rate is 14 vs 6 for the opponent. However, the serving accuracy goes down in G2 and G3 and this results in a complete reversal of the kill rate.
