Rod mentioned:

I'd disagree with that. Using the Mannheim Formula, you can automatically
screen domains for fast flux characteristics, and you only need human
review as a belt-and-suspenders backup to insure that you don't 
accidentally tag something that shouldn't be tagged (false positive).

It is the difference between "every antique painting submited to be 
auctioned needs to be carefully scrutinized by a specially trained 
anti-forgery expert using complex and arcane methods" to "anyone 
can spot at least some forgeries by virtue of the fact that rather
than being painted on canvas, they're printed on heavy paper stock
with a Posters-R-Us barcode on the back."

There's also a risk of false negatives (missing a real FF domain that
doesn't trigger the formula, although it is hard to see how that might
work if we're really talking about a true fastflux domain).
