placement groups        : 13991

A. lead-in prepended to the shifted times is non-decreasing
   13991/13991 = 100.000%

B. non-zero lead-in is strictly less than the next time
   5058/5058 = 100.000%
   control (another group's lead-in, same bundle): 35837/50580 = 70.852%
   gap to the next time, most common: [(10, 2076), (1, 2022), (30, 116), (40, 80), (12, 78), (90, 78), (149, 78), (20, 78)]

C. constant d(alpha)/d(time) across a multi-segment ramp
   corrected (time precedes pose): 857/1540 = 55.649%
   old       (+36 is own time)   : 0/1042 = 0.000%
