In the Elo model, C would be over one class interval (+240) stronger. B the average player (=0) and A over one class interval weaker -(240). The Elo model predicts a win for C against A with 95% probability (rating diff = 480).

In a real world example, A, B and C could be equally strong. Where C is the "fear opponent" of B and B is the "fear opponent" of A.

In the Elo model, C would be the world champion (+1558). B the average player (=0) and A the beginner (-1558). The Elo model predicts a win for C against A with 100% probability.
