Joseph,

thanks for testing, I've added it to my data table. Indeed Beta 9 is about to
become obsolete, but the data is still very useful. I want to be able to attach
rating differences to the changes which I make, even after I am convinced that
the changes were productive. (Which I now am re. Beta 9.) Search is a very
strange thing and quite often I still guess wrong.
