WhisperzQ: That depends on the results. In an ELO system, the true rating of someone how has won all games can't be determined - any rating will be an estimate that's too low. Ratings are not absolute, and they are certainly not points you collect over time by winning. Difference in rating gives an expectation of the outcome of a game (or series of games). A rating of 2600 means that it's expected someone wins 50% of the games against someone else of rating 2600 - and N% of the games against someone of rating 1200, of some value of N strictly less than 100. If someone has won all his games, even if there are only 4 games, he has exceeded all expectations of the rating system - and 2600 will even be too low.

Once again, there are reasons why there are provisional ratings, and why there are established ratings.
