For each N, wobble_moved(N) is the 90th percentile (nearest rank) of entered plus left over the 1 percent trials, wobble_shift(N) the same for max_shift; change_moved(N) and change_shift(N) are the medians over the 10 percent trials. Choose the smallest N where wobble_moved(N) is at most floor(N / 4) and change_moved(N) is greater than wobble_moved(N). reshuffle_min_moved is wobble_moved(N) plus 1, never below 2. reshuffle_min_displacement is wobble_shift(N) plus 1, never below 2. displacement_separates is true when that minimum is at most change_shift(N).",
