Traditional ELO performance rating calculations use the +/- 400 point rule. If you win all your games in the event, your *maximum* performance rating is limited (capped) at 400 points higher than the average of your opponents. Thus your scenario above would be impossible. I realize there are other software calculators that do not use the +/- 400 point rule, but then I don't consider them to be ELO based. [They may be considered alternative rating systems, and worthy of experimentation or implementation, but they are not really the ELO system.] --Steve
