You even cant get an idea. 8.0.0.8 and 8.0.0.23 are almost equal.

A programm can be more than 100 points weaker and can play a certain position
almost perfect and the stronger program can play this position like something
which is rated <1800.
You play with opening book for both sides and with this scenario a 2500 program
could draw or win a 10 games match against Shredder 7.04.
