OK. We understand all of that. And may I say what a fascinating story
it is. Sadly, it appears that just as you began to give us numerical data,
you suddenly ran out of gas, and stopped writing before you could ask
the question !
The only facts I can offer that might somehow relate to the story are:
-- 1 square yard = 0.83612... square meter
-- 1 square meter = 1.19599... square yard .
As for today's exchange rate on the London market between Tepizes
and USD, I can find no information on that.
I can only hope that I have been helpful to you in some small way.
