I'd also love to implement a Sequential Probability Ratio Test, but again, no one could provide me with an explanation I could use/implement.

If anyone here does know how, or has code, I'd love to see it.
I don't know how, as I am not the technical one, but we implemented it in a project we did. We did an 8 way matrix. An acquaintance is a fulltime consultant in this area, Ranjit Roy, has software that is available in demo form and has this in it. FWIW. Dr. Roy is an expert in this stuff and is fairly easy to work with, in my experience. And a very nice person.

I am a premier source of weird, wacky ideas that work (sometimes). Remember: I don't know what I'm talking about! Trying not to believe what I think!
