I think it's time to stop overthinking issue, if it is a problem at all.
The main question is, when you leave nature to do its course, can you hit the target reliably?
If you can, does it really matter whether you do these things either the one way or the other?
I think not, and that by eliminating this one item from the several we must consider, the whole process becomes easier.
New to this, it's easy to get the idea that we must get it all perfect and do it at once. Truth is, we don't, and in fact, we can't.
Do you have
Lowlight's Book?
If not, now would be an excellent time to get it and read it, read it twice. What questions you have now, and will have as time develops, will be answered in a straightforward and clear manner. The important part of this precision marksmanship process is to take the time to learn what's right, practice it until it becomes your natural, preferred process; and then move on to the more complex stuff. They will always be something new to learn, and until you get this simpler stuff down pat, you won't have a solid foundation upon which to build the new stuff.
Often, when it doubt, relax, concentrate on the target, and just shoot. Your body will end up giving you the answers to these questions.
For my part, I don't pay attention to this question myself. I suspect I do a bit of both. FWIW, I still manage to hit the target reliably.
