I don't need to make excuses so you can put that thought away. I 
would certainly  like to compete, or can't you tell?

Great - please post the urls and/or company names and I will contact 
them. France's website wasn't terribly helpful - I was given a list 
of distributors in the US only.

At who's cost? I don't expect you've noticed the NZ/US exchange rate 
lately. I have to earn something like $2.50 for every dollar you earn.
So cost is a factor and I can't afford to front up with more dollars 
than you guys seem to have to in order to compete. Nor should I have 
to.

I concur that it would be fun to compete on an equal footing. It is 
also true however that the "boring" mathematical formula would take a 
lot of beating. Have you compared your results with its predictions?

Agreed. I already know the approach I'd take (and will take if I am 
able to).
