DL,
This would be good topic to discuss at the Conference in August.
Since I wrote the article I feel I should reply.
Square Rule was developed, as I understand it, to use with roughly (not precision) square hewn timber. The French (and English) scribe system is still being used for restoration work (and much new) that is still done with very irregular timber, for the "look" as well as the historical accuracy. I would think the Germans and others must still run into this and would default to scribing after the timber gets so irregular.
