Default Empirically Confirmed Superluminal Velocities?

It's completely unnecessary to synchronize anything.

Hi Bilge.

Why is it so difficult for people to imagine group velocities as wave
envelopes!

All decent empirical wave-group-velocity measurements show that they
are much lower than phase velocity in the same dispersive medium.

I wish to make an analogy to establish a law.

When many people walk in a corridor while their legs are not equal in
length and their steps are not synchronized the group velocity of the
crowd is obviously slower than the fastest person in that crowd.

When six sportsmen are rowing a boat the speed of that boat is the
same as the collective speed of that synchronized group.

The envelope of the rowing mechanics may not exceed the speed of the
boat and the boat tip-front must lead at all times and never be
exceeded.
