I fail to see how this argument has mathematical support. Sure if you have pool of players that have none or only very poor connetion to the outside world, then their rating will eventually become rather uncorrelated, naturally. But if they from time to time play weaker players, then a connection is created and correlation established again. It doens't matter if the other players are 200 weaker, rating formula should adjust the ratings according to the scores. If you have two large pools with players (e.g. Europe and Asia), and just a fraction e.g. 10% play eachother, then that should calibrate the scale pretty well, of course it doesn't get anywhere near 10% so it doesn't work in practise. But you don't have to play round-robin to get a good rating scale, that's the point of the whole system. -S.
