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

The cause of the changed rate is that "the
gunner moves between shots.".

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.

No, it is higher because "the gunner moves
between shots.". The distance between the
rounds in flight is another effect, not the
