Ok, Yaffa, now I'm curious! I've got to get that pressure gauge back and play
around some more. What you found was what I expected but didn't find. And of
course I can't find the notes I made at the time either. What I remember is
that there was some disparity between different pumps but that it seemed to be
minor.
For single pumping I just used the rubber stopper in the breast shield; for
double I put the stopper in one and my personal non-lactating breast in the
other. I only did it with the bottles empty.
I'd rather believe your results; I'll have to try it again when I can get a
gauge.
