You're talking about it, and you're *trying* to demonstrate it. But your
demonstrations are consistently undermined by other factors you consider

Nonsense. See http://jeffjonas.typepad.com/IRAHSS_Expert_Counting.pdf,

"Perfect" is hardly the issue here. I encourage people to read the paper.

I encourage *you* to read the paper, too.

 Not sure what you mean by "exhibit" here. Your queries timeout, so unless

And as I've said before, this is an impressive technical accomplishment. But
it's not always helpful for people. If I have to page through 20 straws of
hay at a time, that's not what I mean by searching the haystack.

Perhaps so. Somebody want to describe the practical use they're making of
this data?
