It appears to me that everyone has the same goal to load more accurate ammo. That means more accurate on the target. Some people are willing to go to every extreme what ever that is to get a bullet to land as close to POA as possible. Some people fully prep brass and weigh sort all components. Some don't because they can't see the difference on target. I have too shot my very best group with neck sized brass but I was never able to repeat it. So I started looking for a better way hence why I joined this group.
Now I fully prep my brass and after firing I bump FL size my brass to fit my chamber with no bolt resistance which is about .002 shoulder bump.
If something else works them that is awesome and more power to them. Like JE said it is what works for me that counts. The two above videos show two different ways to size brass based on each presenters experience.
I also think we may be talking about two different types of shooting.
Most long range shooting matches require a lot of rounds down range in a single day. Obviously they don't load on the range like BR shooters do. It stands to reason that lots can change during the course of a day. Temperature, wind, dust, sun on your gun for part of the day, etc, etc, you get the picture. To load a batch of ammo that will only fit one condition would not end well at the end of the day long match. So he will FL size his brass with a .002 shoulder bump so it will fit the chamber all day.
If just the smallest group one time is the goal then most will neck size only and some don't even size the whole neck so it will align with the chamber perfectly.
As hunters we want to be able to shoot when ever the game presents its self whether that is early morning at 10*F or in the afternoon sun at 50*F or in the snow or rain. So most of us bump our shoulders so the ammo fits all the time. Is that the most accurate period, I can't answer that question because I will not chance it. I have on two different occasions seen necked sized brass not function in a firearm while a big buck was standing broadside to the frustrated hunter.
I will say that once that bigngreen built me a precision firearm then the burden was on me to load ammo that would let his precision work shine.
All this talk of precision reloading and slight differences in sizing Technics is for naught if the chamber is not straight with the bore.
One last thought is that since pressure is equal in all directions a little clearance is OK to help the case align with the chamber as it expands.
