Alex, Thanks for taking the time to write this. It is much appreciated. I am going to go very quiet for a few days while I make sure I completely understand it. It looks like experimental evidence is needed. All, I used to take the view (before I retired) that if: you found the right expert; were convinced they understood the problem; and then took their advice - that you didn't need to fully understand the topic yourself - indeed there were more complicated things about than one person could understand completely. Although I'm minded to trust Alex on this, perhaps it needs just a little more understanding on my part than usual. Thanks to all for their forbearance with the old fellow.
