I use the Mopar decal because with an accurately marked damper I can set the valves on the same exact spot every time. This way you can keep records and notice if something is going wrong. If you use the other method you may not be at the same spot everytime.
BTW I looked at my cam while using the Mopar method and they are indeed on the base circle and I have a fairly radical mechanical roller.
