SM3 refresher question

[Jakeb203]

Shannon, we talked about this before that if you have enough statements repeated that they become self sustaining and generating, would you still need to run the refresher from time to time? It says in the instructions that doing the multistage re-run every 6 months apart is recommended. What if you have had run enough times already? How do you know the statements have become permanent? And do you still need to run the refresher anymore.
