SSDF figures are _perfectly_ accurate.  But only to predict outcomes between
the players on the SSDF list.  They have _nothing_ to do with the human Elo
rating system as provided by FIDE.  Other than they are computed using the
same formula.  But to compare a 2600 SSDF rating to a 2600 FIDE rating is
simply comparing apples and oranges.
