# The (order x shift) table at Csn=2, one axis at a time from the overshoot,
# so a failing cell identifies WHICH knob it needed. Reference: 28.57 s.
# Ladder 2 (after L0-L3 of the first ladder): the stationary polynomial
# wants a LARGER shift than the adaptive one -- it must suppress the
# high-mode deviation on average, not per call. Measured (Csn=2):
# (12,1.0) 48 outer 31.4 s (8,1.0) 58 outer 30.9 s (8,0.5) 60 outer 34.3 s
# Reference (adaptive, Fso6/Fss0.1): 56 outer, 28.57 s. So walk the SHIFT UP
# at orders 8 and 6, trading shift against order. Nrhs=1 is the target.
# name Fso Fss Csn fine coarse
