I don't think that. I also don't have a diseased faith in simulation,
since I used to write them.

But you should have a fairly concrete faith in aerodynamics, especially
with an airframe that's already *flying*.

You can predict lots of things, but you
don't really know what's going to happen until you put a few thousand
hours on an airframe under operational stresses.

You don't need a few thousand hours on an airframe to figure out the
fuel usage. It's a fairly simple thing called "math."
