Given the format of these series of games makes it totally unique in the sense that no human GM was "measured" this way - IE: having to face opponents with months of prep time? It may be safer not to extrapolate too much from this event. I think it should just stand on its own where Rebel achieved such and such a rating based on the parameters outlined by the event.
