In my experience, most of the supertuning techniques are not noticeable by 99.9% of archers. I will not say 100% because there might be someone that did see a difference. I am not the 0.01%.
I will say, I can shoot. In my experience, you can group tune arrows, but unless your bow is very out of tune, you should be able to set it to spec with the intended cam lean and center shot position and shoot it with field points. The difference in accuracy in field points between a super tuned setup and a well eyeballed setup for me is so minimal that I have to be analytical to see it. Just shooting and anecdotally observing, they are the same. That means a lot of time and energy for a very small gain. If you are in the camp where 1/64" could make the difference between winning and losing a substantial sum of money, it MIGHT be worth it. For casual shooting and hunting, it is not worth it for me personally. For my hunting bows, I get a decent tear and then broadhead tune. For 3d and indoor, I set up the bow to measurements and shoot. If it seems like there is a problem then I will paper tune and maybe bareshaft tune to flush it out. I don't shoot fita, but I would think that is the "benchrest shooting" of the archery world.
The harsh reality, for most, better technique from more practice will shoot better than the little bit that can be gained from endless super tuning every time.
