lack of coherence confirmed, probably weak signals, check some influence from the bench position:

move SPRB:
1211188450  May24,18-09:14:10 UTC  (May24,18-11:14:10 CEST)
(B4 seems a bit off centered, adjusted)


move SDB1:
1211189279  May24,18-09:27:59 UTC  (May24,18-11:27:59 CEST)

when centering B1 PD a drop of power on B1 QD -> dead zone? (see plot B1_PD_QD_centering)
