I believe when Jeff Rodgers set the World Record on his Goode, the stock setting for depth was 2.449, and before his round he was heard by Schnitz or someone talking about a scant "half or one or one" depth adjustment, so thinking it was 0.0005 or 0.001.
There are skis that you could almost throw the fin in backwards and run a pass and there are others that are very sensitive to minute fin adjustments or binding moves. The old Goode skis were 2.449, .690, 6.872 jaws with the correct Mitustoyo caliper, I don't recall the tips adjustment but it was north of 6.900. I found the 9100 and the 9500 pretty sensitive to very minor changes. Whenever I started skiing lousy, I would go back to reference stock and reset my skiing.
