I wonder about your ability to monitor the frequency of *not* doing something (i.e., not stuttering) by the frequency of *not* remembering something (i.e., forgetting). (my point is, how do you measure something that doesn't happen each time another thing doesn't happen, i know of no way to do so). So I wonder if you're actually selectively biased by the fact that you "remember" you stuttering because in that moment you recognize you're stuttering.
