Hi Roy,
?
If I thought I could write something on the topic that would get past peer review, I would try! This is many steps below that, and it's not just references that are needed. A much more mathematical model to deal with these issues is sorely needed, but to create one properly would take me, I think, a second PhD. For now, this is just my garden-shed tinkering, given to the group in the hope of provoking discussion and raising interest.
?
Cheers,
?
Iain.
