OK, but supposed you get with your tests that program A is stronger than program B by 50 points, testing them without books. Now if you test them with their books and you get that program B is stronger than program A by 50 points, would you think that the book of program B gives 100 points more than the book of program A? I do not think this would be the case, so I think these testings can only mean that in these specific positions program A play stronger than program B. I know a few games do not mean much, but I made similar tests many years ago and stop making them because I thought I could only get specific data and not general data. This is why I am telling you.
