Paddy was asking us to give a rough estimate for the number of implants per spill.
I zoomed in on the rates histogram (attachment #2) and it looks like roughly 5 implants per channel in SSD 1 and SSD2.
So this is 5*128*2=1280.  Note that I don't know the rate window size (e.g., 1 second, 1 spill?)  Probably the window does not catch a full spill.
This might be an over-estimate because an implant in SSD2 may leave a signal in SSD1.
Paddy was getting around 1k or 2k fragments per spill, but to first order it seems consistent.

   Near R9_372 they slightly opened some FRS slits, as there is a belief we may be blocking some of 94Pd.
   Implant rate seems similar to before, see attachment #5
   Biases did not change more than normal, see attachment #6
