I believe the non-linearity of the expected results function (a bell curve)
goes all the way back to the Elo formulative work, it's just that earlier
versions of the ratings software (prior to 2000) tended to use a linear
approximation of the formula because it was easier to program.
Having spent several weeks in January making sure the new programming came
up with the same results as the old programming, the linear approxmation
has to have been much easier to program.
But as I said before, if you have concerns about the formula, take them
up with the Ratings Committee. I just wrote the program, not the formula.
