To demonstrate the roller coaster method of regaining control of runaway stabiliser in the simulator is a five minute exercise at the best. That five minutes might one day be the most valuable exercise on an emergency the average pilot might see in his career. Just one demonstration is all you need and I guarantee you will always remember it. It does not have to be practiced every year. Yet we spend 15 minutes wasting time on engine start, push back and taxy to the holding point without any qualms.
