To add to the other replies that something that might work in some scenarios - as others implied, most of it boils down to what you actually use NetFlow data for - is collecting traffic levels from a different source, ie. SNMP, and see how NetFlow compares to that over time (ie. under estimation patterns, how much, etc.). Awareness is capital: it can even drive to fixes/workarounds/etc that might work from you.
