If the Pythagoreum method had been presented to Sidney Brown, I'm guessing that he might have excused himself from the conversation. Given all the variables that affect tuning, a few cents this way or that may play in the lab, but not on the stage.

Iry Lejeune didn't fret too much about tuning, he just played the music, and delighted his audiences. Talent and style trump precision en la poussière.

The early Cajun builders including Brown copied German box tuning.

It is not necessary to know anything about something if you copy.

The more I learn about tuning, in it's broad sense, not just cents, the more confused I get.
