I am disappointed that all versions does not include all versions.

Gambit fruit had one game in the previous list and the first interesting
information was to see the place of Gambit Fruit.

First I thought that Gambit Fruit dropped in the list maybe thank to some bad
results in more few games that it played but then I discovered that latest movei
is also not in the list.

I guess that not including all versions is because of the comment of Eduerd
Nemeth who complained about the fact that Gambit Fruit appeared in all versions
and it seems that his comment was counter productive.

I prefer to see rating list with all versions even if some version has only one
single game.

I do not jump to conclusions based on rating list about which version is better
and I only prefer to see more information and not less information.

You can also decide to drop out of the list programs with less than x games for
some x because they may change the rating of other programs but even in this
case it is going to be nice to have a special table of performance of programs
with less than x games.

Note that if you do not include programs with less than x games for the rating
list for some x then the number of program with less than x games may increase
and you need to repeat the process until no program has less than x games.

I do not know if not including programs with less than x games for some x can
help to have better rating list for the programs with at least x games.

disatvantage is of course that the list is going to be based on less games but
the advantage is that programs with little number of games cannot distort the
rating of it's opponents.
