This is an earlier experiment. Read the amendments below before treating its findings as current.
The question
The design predicted that many craft converging on one landing pad would use up most of the safety margin.
What was tested
We sent 150 craft to one pad at once, with a hard ground floor, and counted every moment a pair spent inside each other's safety bubbles.
What was found then
All 150 landed. But around the pad, pairs of craft spent 2,498 simulation steps inside each other's bubbles. The closest approach fell to 0.47 of the required spacing (below 1 means a safety bubble was entered). Traffic on the way in was nearly clean. The final merge onto the pad is where safety is lost.
What we learned later
The same commit's results file and README report the run with the hard ground floor: 6,931 steps inside bubbles and closest approach 0.30 of the spacing. The logged 2,498 and 0.47 came from before the floor existed, when craft escaped the crowd by diving underground.

What changed
Nothing (the hard ground floor was already in).
