the following numbers have _nothing_ to do with FIDE ratings, as they

The SSDF could add 400 points to all their ratings and they would still be
perfectly valid as the absolute value is _not_ important in ELO.  It is
the _difference_ between two player's ratings that predicts the outcome of
the game/match.
