Jack,
Then I suggest you change your definition to "the
total kinetic energy before the collision is the same
as the total kinetic energy after the collision". I
think this may reduce confusion with "conservation" of
energy or momentum where these quantities do stay the
same (are conserved) throughout the situation under
consideration.

It's the same before and after the collision.

Jack,
Please define what you mean by conserved.

I suggest that the definition of "elastic collision"
be that kinetic energy is conserved in the collision.
This definition agrees with accepted practice in every
frame, classicly and quantum mechanically.

Jack
