"I believe that part of the certification process to allow an aircraft to be certified for intentional spinning, is that it will recover itself within a reasonable time, with no pilot input, assuming C&G and W&B limits are correct."
Nope - the requirement is to recover within one and a half turns. The "standard" method of spin recovery is often used but some aeroplanes may require specific control actions to recover with that time. For more info on spinning Cessnas take a peek at:
