You do realize that lots of verses have commonalities like this when it comes to power-scaling, right?
Naruto, Bleach, Dragon Ball, Fairy Tail, Devil May Cry, God of War and many other verses use these methods for power-scaling their characters. Saying that they aren't valid doesn't exactly do justice to these verses at all.
Just because they have something in common, doesn't mean that should be added to the criteria.
In that case, I would like to ask:
Why would the energy system being tied to one's life-force not work as a viable criteria of scaling their powers to their physicals, if shown that they need it to perform all their activities and that they would die or be severely crippled without it? This is a common trope used across several types of universal energy systems where powerful-enough attacks are shown to be severely exhausting the character (Be it by exhausting their magic/energy reserves tied to their life force or by exhausting their stamina reserves to which their abilities and physical characteristics are linked).
Why would using the same energy type for all their abilities and physical characteristics not be a viable criteria for cross-scaling said abilities to their physicals, assuming it is proven to do so? Do note that this would not limit the character from using different energy types for the same purpose as the main one.
These are basically all the supporting criteria that's left now, since most of the others would be relocated to the Notes section (Criteria 3 and 4), Criteria 5 would be moved to being a sub-bullet point for Criteria 1, with only Criteria 6 and 7 remaining unchanged as of now.
These guidelines weren't just made out of thin air, they were made based on observations of how each of these energy systems work, so as to tackle the basic major functions of these energy systems, the functions that allow for scaling abilities to physical statistics.
What noise exactly? How do you exactly evaluate every verse on its own without knowing where to look and what to look for? These guidelines are literally tips and advices on how to do all of that.
Also those two questions are already in the draft, Criteria 1 and 7. I suggest you check those out as well. If DT's suggestions of bringing back the "Mandatory" and "Supplementary" headlines are carried out, Criteria 1 and 7 will become the two mandatory criteria to fulfill to qualify scaling the energy source to physicals, everything else after that will be supplementary criteria.
I think the "noise" would be anything besides the mandatory criteria. If all you need to qualify is one (or both) of the mandatory criteria, and the supplementary criteria would never be enough by themselves, why include them?
This is assuming DT's recommendation of adding back "Mandatory" and "Supplementary" is passed through, granted I myself and many other staff members have voiced our disagreements with giving out "Mandatory" and "Supplementary", while holding stock that the two criteria are the most important of them all. The guidelines were always meant to function in a similar fashion to the Lightning Feats page and the Light-speed Criteria page, where you would have to fulfill a bunch of criteria but you wouldn't have to fulfill all of them. Maybe we should have mentioned that as well, but that'll be irrelevant if we bring back the "Mandatory" and "Supplementary" headlines. Also saying that the supplementary criteria would never be enough by themselves is just, wrong.
