Really?!? Before I wrote my mail I checked and did not see the disclaimer.

Now I rechecked. There is no disclaimer. So why is he saying, there is a 
disclaimer? Check again. Oh, it's in the title bar of the window, not in 
the window! I never read title bars unless the windows is minimized. Am I 
the only one?

The other thing is: It's not the point that it is a simulation. Simulation 
is what everybody does, you cannot do better. The point is that we have 
just implemented this and have only checked it maybe against a dozen dives 
with other programs. It's more testing that would make me more confident, 
not the fact that we are simulating a complex system with a simple 
algorithm.

Best
Robert
