difference in rank = number of handicap stones
is very convinient ofcourse.
An alternative way to look at this is to say:
if player A beats player B 70% of the time in an even game(with komi)
player A is 1 rank higher.
(Ranking systems make this kind of presumption. Maybe somebody on the
list can supply the value KGS uses)
This would accommodate an almost infinite number of ranks within the
span of the last stone towards perfection.

For amateurs, rank is defined as the number of handicap stones for an even
game. For pro's it's somewhat arbitrary, depending on good results in the
rating tournaments over many games. Of course Elo is a European chess
concept and is not used for traditional games in Asia. A 9 dan pro is
perhaps two or three handicap stones stronger than a 1 dan pro, so there are
more than one pro rank per handicap stone.

Clearly being able to given a stone and have an even match is not what
is used to define rank. Is ELO used to define rank? If not, then
isn't it a largely arbitrary measure?
