Assuming peak Revan, I can see him clearing, but I can also see him falling at round 5. Anakin is a better swordsman and is comparable in power or even more powerful than Revan. While I think Revan can defeat Anakin alone, due to his greater array of powers and mastery of the Force, I'm not sure I can see him handling Anakin while Kenobi is running interference.
So stops at 5, most likely.
