My pleasure. And I often can't help myself with the stupid details. All this problem solving is equal parts maddening and satisfying. With endlessly below average temps and crappy weather here I am looking for things to fill my time and, I am happy to add what I can to the body of work for anyone else that might wander through like I did, filling the gaps and questions I had and building on all the good works and research of those that pioneered these things at the start. I am really thankful for that and all the help I receive here so I feel it's my small way of paying it back.
