Sampling efficiency diagnostics for the HXMT Crab example. Top: distribution of wall-clock sampling times over 100 repeated fits for ELISA/NUTS (blue) and XSPEC/GW (orange). Middle: distribution of effective samples per second of each fit for ELISA/NUTS (blue) and XSPEC/GW (orange). Bottom: bulk ESS as a function of total sample count for the same repeats (one thin line per run); the dashed line marks ESSbulk = 400.
