Hi, thanks for the suggestion. We did consider a synthetic step inserted before the real interval step, but it does not quite fit the use case. WorkoutKit surfaces every step in the watch preview, mid-workout indicator, and HealthKit history. A synthetic 15 second step appears as a real step in all three, so the runner sees four steps in their interval (recovery, prep, work, recovery) instead of the two they actually performed. The recorded summary later does not reflect the session structure. The step transition haptic means this step starts now. A pre-roll haptic should mean the next step starts soon. Using the transition haptic for both makes the two cues hard to tell apart.
