... a significant waste of money!

But it won't be - they computer post-process the data, and answers they get 
will be have to be probabilities. So they will say "almost certain" or "very 
likely". And the calculations can reasonably only be done on their own 
computers, and so the realistic options for peer review are zero, the 
incentive for exaggeration is enormous.
