A bar is the time from the previous contact to this one, drawn on the side of the player who struck it; the shaded band is the mean of the last 3 gaps, so a bar poking out of it ran longer than the rhythm around it. A gap counts as a tempo break when it is at least 1.5× the tempo in front of it, or that same factor shorter, and at least 350 ms away from it either way — the ball before it either hung up and bought the striker time, or came back fast enough to take it away. The serve ends no gap, so it is a tick on the line.
