FindBeamCenterFromSpotSymmetry calls Estimate() five times - once for the answer and once from each
of four starts 25 px away - and three quarters of each of those is an 861-point brute-force grid
over the spindle. So making the uncertainty gate live was paid for by multiplying the estimator by
five, which is the whole of the pre-scan's cost.
The four restarts share nothing: each takes its own copy of the geometry and only reads the spots.
What is wanted from them is a max, which is order-independent, so running them concurrently gives
the same number. Measured on three rotation crystals, the committed centre, the reported sigma and
the fitted spindle angles are unchanged to every printed digit.
