I mentioned to John Walker that the pseudorandom data generated as a
clone to the EGG database by an algorithm he wrote is invaluable as a
source of "control" data to check our analyses. In particular, the
cumulative variance figures do not lend themselves to ordinary
statistical assessments, but visual comparisons of the real and pseudo
data provide some indication of how likely the variance behavior is. He
sent the following response.

Yes--I have been following the results and they are
stunning. I've directed several people who've contacted
me to the results page and even the most skeptical
have been taken somewhat aback. Once again, there's
that remarkable "leading indicator" effect, particularly
notable in terror10-12vp.gif, which is hard to
reconcile with any conventional presumption of
causality. About 20 years ago I was very interested
in modeling the behaviour of financial markets, in
particular, the way they "anticipate" or "discount"
events--that is, move in advance of the news. There
are, of course, perfectly mundane explanations for
many such events (viz. the current investigation of
suspect trading in advance of the terror attacks), but
there are other cases where it just seems like the
collective consciousness of the market is picking
something up in advance. In fact, one might say that
the global financial markets were the first consciousness
supercollider. As an aside, the pattern of the real
data in the terror10-12vp plot would instantly be
recognised by a stock market chartist--"ink-stained
wretch"--as a "head and shoulders". Note that the
"break-out" above the peak of the left shoulder
is well in advance of the event and forecasts a
run-up of at least the size of the left shoulder--right
out of the 1954 edition of Edwards & Magee!
