No doubt that human vs computer is more relevant than computer vs computer
and certainly at 40/120.

In the early days of chess when computers played on a 1700 elo level it was
a lot easier to conclude which program was the best against humans. These
days when a chess program loses from an IM you have done very badly, when
it draws the IM has done very well and finally when the program wins nobody
is going to be excited about it because nobody expected otherwise.

Nowadays you have to play GM's only. I formulate the impression I have got
from postings here and elsewhere: a loss is accepted as long as the number
of wins is the same or higher. A draw against a GM is nothing to be excited
about but the computer did very well. A win is what people hope for and more
or less expect these days.

Competing on this high level has the big disadvantage that the number of
available data (games) will remain very low because GM's don't play for free
and it will be very difficult to judge the state of art in the ongoing battle
between Man versus Machine with the few games we have until now.

Computer versus Computer is a world of its own. There is a massive number
of data because almost every program supports a device for automatic play.
Next, comp-comp is very popular and big fun to do. It's logical people create
rating-lists from the data like the SSDF people for instance.

There is nothing wrong with the SSDF list as long as you know how to interpret
the list. These interpretations are discussed here from time to time and IMO
they keep the balance regarding the value of the SSDF list in a good way.
