So you got a list of people who don't care for blitz matches. Maybe they have
some anecdotal evidence showing that blitz matches are useless. But has anything
seriously been done to prove this?

Experiments have shown that computer-computer match results can swing wildly,
even if you play 100 games. So if you really want to prove that blitz match
results are useless, it seems to me that you would have to play two matches of
at least 100 games each between two programs. And that would just prove that the
blitz results are useless for _those two programs playing against each other_.
It would take a tremendous amount of effort to prove that blitz results are
useless in general, even if you only take the top dozen or so programs into
consideration.
