    I suppose it's possible but I meant the old boards I've seen typically are a
bit thicker on top. On the other hand as far as a general board thickness
parameter between even the same models does not exist.

Ah, yes. Well, they were thicker back before the "Diaphragmatic Soundboard" was
invented back in the early 1930s. We've replaced enough boards in pianos made
through the 1980s and 1990s to see some of the results of boards this thin
combined with compression crowning.
