In Response To: win probability for a PR difference and match length (Rico)

What is the source of this formula?

Spontaneously, I think that there is less difference if a 1850 player meets a 1950 player, than if we compare 1500 players face a player with 1600 in rating.

But both games have a D of 100.

just my 2 cents
