Exactly.

I was however wondering whether there is a quantitative model/measure of the effect explained on the page down your ling... fully recognizing that it would be a rather 'hot' if not controversial thing (depending on where it came from).

Love the 'deep lustre' wording; new to me. It sounds suggestive in the right way, appreciate the relation with the nature of the phenomenon, clear as two words can get, etc...

Thanks for the reference !
