The stall rule ('step not below 0.9 x its best for five rounds') called a steady slow fall a stall -
82 of the 245 loops that ended unsettled in the rc176 full battery were still falling at < 2% a round -
and every unsettled loop returned its LAST state: a fulls loop that diverged from round 1 handed on
the state after five rounds of walking. Now a loop is stalled when the median of the pairwise slopes
of log(step) over its last six rounds (Theil-Sen) is not negative - a median, because a least-squares
slope let one round's jump (the smoothness re-chosen five decades away) end a loop falling by a
quarter a round - and however a loop stops (settled, stalled or at the cap) it ends on the plain round
with the smallest step. On a settled loop that is the last round, so nothing changes there; on any
other it is the state closest to a fixed point the loop reached. The partials' loop restores it
through the round's own rescale (ratio fitted G / best G), so the corr bookkeeping of the CPU and GPU
paths is unchanged.
