Why it went the way it did
R won 0.0 more points than R relative to what the serve alone predicted. R's biggest leaks: return execution −16.5, forehand execution −6.3, backhand execution −2.8.
Each shot moves its hitter's chance of winning the point. Those moves are split into direction choice, shot selection and execution, and summed here. Read both columns together: one player's gain is the other's loss.

Counterfactual: the best direction every time
If each shot had gone in the direction that is usually worth most for that stroke and position, this is how many more points each player would expect to win. It's an upper bound: the best direction isn't always on, and the chart can't see the ball's pace or position.
