My data for vAg calculations were deleted from APUG during an argument on-line here about two years ago with another APUG member. It appears that they are GWTW and I apologize. I will have to recreate them entirely from scratch if they are to be in any useful form.

And, the spreadsheet of data was erased by me before posting because APUG did an abysmal job of handling the tabbed data in rows and columns.

Here is the graph generated from the data. Sorry that it is partly incomplete, but I have a lot of work to do to clean it up from my Excel spreadsheet. It is the only JPG file that I have on-hand.
