Male beavers and female beavers behave differently. At any rate we have the raw data in the form of the PGN itself (although some of the very oldest games may not be available) so those calculations can also be performed. I am guessing that there will be no discernable difference. Of course, I have not bothered to try it yet. >>>Now the worst mistake is your permanent presention of numbers and functions, but >>>you always forget to discuss the important question in the design of the >>>statistical method.

We shall wait then. >Why do you write with two "n" in Dann? When they asked my mother what my name should be when I was born, she said: "D - A - N - N..." because she was thinking of 'Danny' But then she remembered that she wanted it to be "Daniel" so she added: "I - E - L" So my legal name is Danniel. I rather like it.
