Sorry Bill, it's good that this forum has a wider mix of expertise then most other forums. Modeling is just a tool and as such only useful to gain some insight in how and why performance between designs differ and can be improved.
I think Asetek made me a mod (I’ve absolutely no other bonds with Asetek then some unpaid ‘free time’ projects and giving some user assistence as a mod!) because I was loosing interest in most of the forum posts, not much new to learn in there right now (still waiting for the Bowman review on the new evaporator).
So keep developing and testing and some of us will try to find an explanation behind your excellent water block performance
