The perfect handicap rule

While I don't mean to negate the good intentions of this Great Lakes group, but the claim in this promotional copy caught my eye:



ORROA (Offshore Racing Rule Owners Association), in cooperation with the Offshore Racing Association (ORA) and Offshore Racing Rule (ORR), has developed a new racing series called The Great Lakes Championship Series. By providing a common rule among different venues on the Great Lakes, boat owners of all types will compete on a fair and level playing-field, as the objective rule does not give an advantage to any boat type.

Is ORR the perfect rule?
