Confession time :{

I have to admit to some self-interested motivation in my earlier post.

Orac, I really appreciate your patient efforts to explain things to me. However, I feel sometimes that my lack of background knowledge prevents me from getting the most from your efforts, and may even cause my responses to add to the problems.

Part of the objective of my post was to try to lure Pete into the thread, as I felt I could learn more from being privy to discussions between you and Pete than I would from wrestling with your explanations alone.

I apologise if anyone’s professional pride was dented. Please consider that as collateral damage in pursuit of a worthy cause.

There never was nothing.
