Why change time to wavelength only to change it back to times? I don't think it is easier but YMMV. However, that's beside the point, what I was pointing out to Jim was what you say next: > It is reduced by the distance the gunner > moves between shots. The cause of the changed rate is that "the gunner moves between shots.". > In the target frame, bullet energy and speed is the same in both instances Exactly, but Jim says the reason for the increased rate is the increased energy. In this counter-example the energy has not been increased, that's what I am trying to get Jim to think about. > .... but > arrival rate is higher in 3) than in 1) because of the shorter > 'wavelength'. No, it is higher because "the gunner moves between shots.". The distance between the rounds in flight is another effect, not the cause. George ```
