Seen from the side of the court: the net stands at the left, drawn to scale on the same centimetre axis — 91 cm at the centre strap, with the court surface that far under the cord. A ball that never crossed has no landing depth, so it is stacked on the net at the height it struck, and every share below counts it. Clearance is measured against the cord where the ball crossed, and that cord rises to 107 cm at the posts — about 103 cm over a singles sideline — so the same figure is a thinner margin out wide than down the middle. The window is the coach's cue (60–140 cm), not a percentile.
Net clearance: L. Marchetti, Club singles · sets 1–2 · rally balls only. 133 groundstrokes seen from the side — height over the net cord in centimetres against landing depth from the net in metres. The net is drawn to scale at the left: 91 cm at the centre strap, with the court surface that far under the cord. 43% passed inside the coached window of 60–140 cm. 11% went into the net and are drawn on the net at the height they struck it. Median clearance 70 cm and median depth 7.2 m, over the 119 that crossed. 53% landed past the service line at 6.4 m, 1% past the baseline at 11.89 m. Exact splits follow in the data table.
Every groundstroke grouped by where it finished, with how many, their share of all groundstrokes, the median height they passed the cord at, and how many were inside the coached window.
