Hey, Every Topic, didn't mean to offend if it seemed that way. I'm all for any approach you suggest and willing to help any way I can. I was serious about the dutching thing. I really don't think I'm too far off with it. Ask around here and folks will tell you I'll put together spreadsheets, databases, calculations, whatever. I certainly do have an open mind, no worries there.

As for mathematical methods, that's what I'm looking for. Actually, I blame Mark for getting me started on this! I've been working with folks on the UK site. There's some great resources and databases for UK.

And if all this doesn't work I'll have to go begging back to Mark. :grin: I'll figure this out yet!
