Shade is share of tracked time per 0.9 m cell; an unshaded cell is a place the player never stood, not missing data. The mean is pulled toward the net by every excursion forward, the median is where the player actually recovered to. Here the median lands 0.37 m from the average — too close to draw as two marks — so the diamond is offset, with a hairline back to the metre coordinate printed beside it. Pick a depth band to re-read every figure over that stretch of court alone.
