BTW I have just this minute had an email in reply from the contact.
That has supplied some more documentation. Not yet had a chance to
look at it, though.

The contact supplied a document. This doesn't itself answer my questions.
But it did direct me to

http://www.russandrews.com/src/resea...rchpaper09.htm

So I have downloaded the relevant 'papers' from their and will study them.
I'll be interested to see what reactions others may have if they care to do
the same.

Slainte,

Jim
