Racing flow benches

In my humble worthless opinion, flow benches are like engine dynos and chassis dynos. Absolute numbers aren't worth much, especially if you don't know the operator, the equipment, and the conditions.
Bottom line to me.... how does it run all put together in the combination.
I would rather have a dyno proven 400 hp that runs hard than a car with "dyno proven 700 hp" that won't fall out of a tree.
