Thanks Dan for your two valuable peaks!

I always thought the 4x factor came directly from comparing file
sizes in the old HP LIF format, but that probably around 1985
when the FACScan arrived in Adelaide.
 From the recent discussion it looks like I just made a 2x error
in arithmetic back then and never bothered to test myself....

One reason I'm still in Flow Cytometry after 20+ years is that
there are always new things to learn; I was not expecting a
lesson in my own fallibility this week.....
