Dick, I have no doubt that your report is accurate and the plane flies great, I've read enough of your posts to respect your opinion.
In this example though we don't have a base line for comparison since this is a one of a kind plane and may fly like it does through configuration and design. My suggestion is to ballast the plane with 10 onces on the CG and report the difference in handling. We know the vertical and stall speed will suffer, but I would like you opinion on the changes in response and aerobatics other than high alfa.
