I can imagine that is the case - however it shows graphics of the flow so it's very easy to get a basic understanding of the turbulence and pressure differences using the different colour overlays and squiggly lines! In terms of air flow I seem to remember just looking at it at a variety of pressure differentials from idle to a boost type scenario. It seemed relatively consistent across those changes so I didn't bother going to deep into that. You can factor in roughness, certainly something pretty significant if I were to sand cast it myself!
I am certain I was not using it either to its full potential, or even correctly, but it was still easy to see what changes had what effects and through that optimise the basic design.
