Dann,
Have you done a win expectancy for a 2500 player to a 2800 player?
The reason I ask the question is that vitor pointed out elsewhere in this thread
that once you get to a certain rating, you only win or lose 1/2 the rating
points per win/loss. To me, this is an aberration in the formula which would
result in a different win expectancy between a 2500 player and a 2800 player
than between a 1500 player and a 1800 player (i.e. the equation should be
different).
Is this the case? And if so, what would be the win expectancy? Would the win
expectancy between a 2500 player and a 2800 player be equivalent to a 600 spread
in the lower ratings?
