"All models are wrong, but some are useful." - George Box

Generally: it is often impossible and/or unreasonable to do an identical 
simulation, model, practice run, etc. That does not mean these things 
will not yield insightful results or info. (It does not mean they will, 
either.)

I haven't looked into any details about the above-mentioned stuff, so I 
have no idea what valuable info can be gleaned (if any); but I'd want to 
know more before rejecting them out of hand.
