Hence the importance of using the same torque settings each time, When the barrel is chambered and the tenon threaded, the shoulder (barrel curve) is indexed..

Unless you have significant wear or either the tenon shoulder, or the back end of the tenon (when using a barrel nut), the difference is pretty much insignificant. Obviously you have different scope settings for different barrels and calibers, but all of that is again, pretty repeatable.

I guess it depends a lot on the type of shooting you do. In fullbore with 2 sighters and then at least 10 shot strings, it is not a major problem. Several of the top guys use QD scope mounts, remove barreled actions out of stocks etc and don't seem to suffer for it.
