You seem to be missing what I said: My instructions are only more time consuming once per type of brass.
I don't think taking the time once to optimally adjust the die is a hardship.
It's similar to the FL die situation. The instructions supplied with them work, but they are not necessarily optimum for each particular chamber. So a meticulous handloader may take the time to learn how to adjust his FL die to suit each chamber for which he loads a given cartridge.
