There used to be a "Replication Conference" (that was the name of the
conference or the organization sponsoring it) that I almost atteneded
one year where they talk about record pressing and tape duplication.
That sounds like an industry group if there ever was one.

I wonder if they took a vote on what you think the definition is, or
just let it evolve and let observers like you draw their own
conclusions.

If the conference was about record pressing and tape duplication,
it sounds like the data point may be expired by now?

This seems to be the current consensus IME...
