EMC2 you rock
you can actually lay down numbers (or atleast lay down the fact that you know them)
the straight science behind it is pretty undisputable, and was what i was looking for.
it would be cool to see someone test with a flow meter too, or the tests with how long it takes to empty 5 gallons.

and everyone else that has posted, thanks. its been putting new thoughts through. if you guys have more to add please do.
