@adriangb I created a fix PR for the inexact_overlap benchmark data — the
previous jitter formula only added overlap between RGs but kept the overall RG
order ascending by min values, so reorder_by_statistics was effectively a
no-op. The fix scrambles chunk order so the benchmark actually tests what it
claims to test.
I also re-triggered CI to confirm there's no regression even with the old
(wrong) dataset.
