GBS16k and GBS32k look alright. The proposed RCPs represent the true distribution very well

The AMD set for GBS 8192 came from three campaigns; the 3 h campaign's
stalled runs were replaced by new seeds, so the 20 runs carry one run above
80 M samples while 20-seed reruns of the reference code show five. The new
entry is 20 seeds chosen as ventile midpoints of a 179-run distribution and
run with the unmodified reference (mlcommons/training b5e8e2a) on 2x4 GB300,
uncapped, each run to the 0.75 AUC target.

Olympic mean 73.02 M (was 69.07 M), std 6.69 M (was 3.81 M), checker floor
68.16 M (was 66.30 M). Other batch sizes unchanged.
