A four-state stamina card — several match metrics stacked as small multiples over one shared minute axis, each read against its own opening-window baseline, with the drop-off after a chosen cut quantified in the metric's own unit and as a share of that baseline.

Each metric is read against its own opening mean, in its own unit — the dashed rule across every panel. The thick dashed run from the cut is the mean after it, and the shaded gap between the two is the drop the readout quotes, printed as the difference between the two values exactly as they appear. The percentage beside it is that move as a share of the baseline, signed so negative always means worse: where lower is better — seconds between points, errors per game — a rise off the baseline is printed as a negative move. A move is called decay only past 1.5% of the baseline, and the panels are ranked by that signed percentage because points, kph and seconds share no scale.
Stamina decay: 4 metrics against elapsed minutes, 0 to 210. Each metric is compared with its own mean over the opening 48 minutes. 3 of 4 metrics are worse than their opening baseline after set 1, by more than 1.5% of it. Steepest: Points won, rallies 5+ at -14.0% of baseline. First serve in play: baseline 64.3%, 59.9% after the cut, -4.4 pts (-6.8% of baseline, negative is worse). Down. Points won, rallies 5+: baseline 56.5%, 48.6% after the cut, -7.9 pts (-14.0% of baseline, negative is worse). Down. Average first-serve speed: baseline 186.8 kph, 184.8 kph after the cut, -2.0 kph (-1.1% of baseline, negative is worse). Held. Seconds between points: baseline 18.6 s, 20.7 s after the cut, +2.1 s (-11.3% of baseline, negative is worse). Down. Exact values follow in the data table. Up to 12 sampled minutes, evenly spaced by rank.

No readings to plot yet
Stamina is a comparison, not a snapshot: each metric needs readings inside the opening 48 minutes to set its baseline, and readings after it to fall away from.
