I don't have anything useful to add except to say that this looks very
promising.  I'm an idiot when it comes to statistics but even I know
what 18 standard deviations means.  Also, having a system that generates
a "confidence" value in addition to a "rating" is a huge bonus.

No time to play with it now, unfortunately.  Maybe tomorrow.
