David, your posts would be easier to read if you would leave put in a couple of line breaks here and there. A solid block of text can be difficult to read on a computer screen, especially when it is packed with numbers.
The problem is that it is difficult to keep one's place when the eyes go back to start the next line.
Hope you don't mind me offering this suggestion.
