(60 to 100 ELO points superior). This is not quite right. 200 rating points difference translates into roughly winning 3 of every 4 games played, (or winning two and drawing two of course, to total 3 points). 400 is roughly 15 of every 16. 100 points is much less significant in that light... and 25 is nearly meaningless unless you talk about a 1000 game match.
