Yes, I think the results are pretty good so far, especially for the
more non-uniform distributions. AFAICS it solves the 2 original
complaints, and I've not yet seen a case where it makes things worse.

I plan to do more testing (and if anyone else wants to, that would be
most welcome), and then barring any unexpected issues/objections, I'll
commit it. Probably not this week though.

Regards,
Dean
