That would make sense. In the context of compression crowned boards,
diaphragmming the panel would lessen and weaken crown, so they would try to
minimize that long grain loading to try to avoid pushing the top half flat
immediately upon assembly. I wonder if they really did do that, and how if so,
much they deviated from plane.
