FYI:  Set my alarm to watch the range for the CP1 fill this morning (yesterday H1 was unlocked), and H1's range parallell's the known telltale behavior following the CP1 Fill signature Dave posts above (i.e. small and slow range drift down puntualized with the 50Mpc range drop when the CP1 Liquid Level Control Valve closes at the end of the fill).  Forgot to look at the CDS Overview to watch the CDS Alarm box go red during the Fill---next time.  :)
