It’s pretty common, particularly in workouts with spiky intervals. A recent example for me is Bashful:
You end up with this kind of saw-tooth wave. You can thumb through the All-Rides for bashful and see everyone ends up with something similar. Another example is Williamson… the overall curve is smooth, but you get a fine saw-tooth wave across a wide range, and illustrates that the more varied the intervals to more peaks you will get.
