just a quick note, for those who might be interested.
I have spoken to the authour of the 'Royalty Model' and he or she has made it clear that it was for his/her paid advisory clients only, and we really should respect that.
if the authour isn't prepared to have his/her information more widely shared, it's not for anybody here to try to force the issue.
as FJ put it, its approach perhaps 'skins the cat differently' ... but the end result is the same.
in other words -- because of the great DD here on the forum -- it doesn't really add anything that we didn't know already.
thanks for your understanding and restraint.
I hope that closes the topic.
cheers,
R.
