I realize that the answer will be complex, but I'm really curious what you came up with here
I quit truing actions ~2004.
I seldom turn necks.
I don't weigh brass.
I don't weigh metered powder charges.
I seat 25-06, 6.5-06, 270, 280ai, 7mmRM, and 300WM all at 3.34" OAL.
I don't use a gimbal in the lathe, I just count on the 6 jaw's D1-4 mount being lose enough to steer with the spider with a minimum moment arm bending the barrel..
