Fox - yes it is pretty technical, but attention to detail is pretty much a requirement with this Poser business. There is often a choice to be made in either giving a pat answer, or trying to show how to figure it out for yourself. I often try for the latter, even if I am usually unsucessful. While it is not a chart, I posted a short description of the figure evolution over on the forum at R-otica this afternoon. This may help explain things. I do not want to Spam all of the forums.
