        Whoops! Sorry, my bad.

        However, assuming my theory that the statistical day-to-day
variance (adjusted for growth) will roughly follow a normal
distribution, then this would be a ten sigma quantity, and I believe
that most people would probably be relatively happy with a 5-6 sigma
(covering 99.9% of the likely possibilities).

        I'd be interested to know what others think on this topic. Folks?
