I've bought dozens of them over the years and talked to crystal
engineers for tens of hours. I watched them plated and tuned at a
crystal filter company in Phoenix. I own Virgil Bottom's book on the
subject and understood half of it.

Have you ever tried to actually *buy* a crystal built to a
specification? There is a
tolerance on them. That has a profound impact on what you can *buy*.
