Hey @jdlbb!
I would exclude all custom workouts from the AIFTP/Progression Levels like @FrankTuna mentioned 
Custom workouts made with the Workout Creator don’t have the same Workout Level logic as the ones from the TR Workout Library.
Like @mailman noted, by not excluding them, you’ll be bumping your Progression Levels and get served a bunch of workouts you’ll most likely struggle with.
The “did not pass” option is only for TR Outside workouts in case you struggled or did not complete the scheduled workout.
By default, Adaptive Training considers completed Outside Workouts to be successful and adjusts your Progression Levels afterwards to reflect this. But just as with indoor workouts, your response to the post-workout survey can add further nuance to how Adaptive Training responds to your performance.
Once your outside ride has been associated with the planned TrainerRoad workout, you can update your survey response on the app or website to rate how the workout felt, or select “I Did Not Pass” in case you struggled with the workout.
Similarly, like with custom workouts, by marking it as such, you are ensuring you don’t update your Progression Levels to a Workout Level you did not complete/struggled with and are ready for.
