The profile the timings come from: a descent into the basin.

The basin rather than the summit, which was forced when the streaming rules measured altitude from the datum: a summit could sit above the fade line and draw nothing at all — Miranda's did — so timing generation from it reported zero and read as free. Nothing measures from the datum any more and every site draws, but the basin is kept as the timed profile so the figure stays comparable with the one the rig first recorded.

Every survey site, flown, so the holes are visible rather than implied.
