Interesting idea.  Won't tell you anything about an infant's intake, though - and I would have thought that intake has a much more direct bearing on whether or not an infant thrives. 
Surely the issue is enough intake or not enough.  Since we don't actually have any good evidence of what number constitutes enough for any given infant (given there is such a wide range of volumes upon which infants have been observed to thrive), we have to use the clinical signs to determine whether any given baby is consuming enough.  The number that corresponds with enough for one infant may well be not enough for another.  Numbers, in this case, are a distraction and could well become a hindrance.

>  to get a rough estimate of a mother's milk production in 24 hrs.  The way you do it is to have a mother pump with a hospital grade pump every hour for 15 minutes for four consecutive hours.  You add the the totals she pumps for hours 3 & 4 and divide by two.  Then you multiply by 24 hrs.  This gives you an estimate of her hourly production and her daily production.
