Hi Dave,
Anyone who goes thru the trouble of providing calcs to support their position is most welcome! This is a tough, but for the most part, fair and objective collection of characters. not to mention that some of them have been around for near 2 decades on this forum. strong opinions, but backed up by considerable experience with bad science/engineering and an emphasis on facts, not theories.
