Hi John S. Yeah sorry about the above. One of those posts I just should have deleted and not sent.
JL said he was making up numbers, which is fine by me, as long as he says he's making up numbers... which he did.
I "make up" numbers too sometimes, trying to estimate some unknown thing. Sometimes it's a good guess.. other times experiment shows that it's totally wrong. (In some ways being wrong is more interesting.)
