Wow, yeah. I was just about to say something about that. I even pasted
it into a notepad and started cutting it apart, but I wasn't sure about
enough of the column sources in all those subqueries.

It looks like it'd be a very, very good candidate for a window function
or two, and maybe a few CASE statements. But I'm about 80% certain it's
not very efficient as is.
