You are a silly boy Marlow... the 1200cc twin/1000cc four rule is based around a piston speed formula. Both configurations are limited to the same max piston speed and twins have a capacity advantage to create performance parity. Previously with the universal 1000cc formula the twins were allowed extra exotic non production internals to reach parity... a stupid idea for production based racing.

Does the 1200/1000cc rule work? Yes Bayliss won the championship, but where were the rest of the Ducatis? Certainly NOT in second,third & fourth fifth position, which would have been the case if the rules were unbalanced.
