Yes, mothers who are expressing for babies in these circumstances
need a guide,  so they know if they are expressing more than or less
than the baby's likely need.

Interesting that those figures (above) are rather less than the
imperial ones - which roughly speaking would be 75 mls (2 and a half
oz) per 450 g (pound), or, again roughly, 165 mls per kg...unless my
maths is wrong - quite possible ; )

None I can think of.  Using these factors (number of feeds and length
of them)  could give you a wildly misleading picture.
