The book is part of the program, as much as the engine! The top programmers try
to make the book fit the program, so that the prog. do not end up in postions
where it dont have a clue.

In that respect I believe you are wrong also. I'm quite sure that you will get
better results for newer program if you match them on similar hardware. I have
not had a look at SSDF list resently, but as far as I remember you find a very
high correlation between newer program and higher on the list!
