In queste condizioni veniva il 70% di SR il 26 settembre

Si sospetta un fuorifuoco della IRTC. Si mette a mano Z=47.7

NO sembra che il best focus a 48 sia meglio!

Proviamo a Z=48.1

Quindi il massimo dello SR e' davvero dove lo trova la procedura AutoFocusIrtcGui e lo SR in questa condizione cambia di 2% con 100um di slitta Z
