David Vizard - Which to prioritize - PORT FLOW or PORT VELOCITY?

my head porter (he is well known on this site) told me don't worry bout the big CFM #'s as long as the port has velocity. i wanted to see a certain flow #. i was a bit disappointed that the flow #'s didn't hit the magical # until i got the timeslips. i guess i didn't need the big advertised flow #.
