I think you'll need to apply a scaling factor so that samples that
accumulate values over a short interval will not blow up. I've been
reading your discussion, and it looks like a really fun math problem.
I'm stuck wrangling servers and cultivating my ulcer for now... but I
hope I can find some time to study it with you soon.
