I'm making this short post because of the few contentions I'm seeing here.
So far, there has been a main issue regarding the approval of Hinata replenishing BSM Naruto's chakra as a feat for her. I'm going to explain why it correlates with her upgrading to BSM Naruto's level in AP.
Firstly, I already linked a
post to KingTempest earlier in the comments that was made by US69 explaining why Chakra+Potency/control=AP. In that post, there was a section that specifically claims that
the more chakra+potency you have, the higher your AP becomes. He made other examples like how
Kaguya became stronger when she took in chakra from the shinobi alliance or how Might Guy became stronger in AP when he
released all his chakra limiters in 8th gate. He even makes different debunks to those who didn't believe chakra=AP.
Like how he debunked those who claim kid Naruto would have been the strongest if chakra actually equaled AP or how he made other debunks such as
this and
this. All these debunks and posts made by US69 essentially mean Chakra does equal AP but it depends on the control of your chakra or the specific ability you use that could be hax-based that increases the AP of your jutsu. So even if Hinata(with Hamura's chakra) had an equal AP with BSM Naruto, Naruto would still emerge victorious in a battle since he ha far better skillsets, stats, and overall better jutsus that are more hax-based.
Even on this wiki, edo Hashirama has a AP tier that puts him at KCM 2 Naruto's level purely because he had more chakra than KCM 2 Naruto;
Attack Potency: As an Edo Tensei, he stated that
he had more chakra than both
Naruto and 50% Kurama combined
[14]
So this is even an accepted method of AP upscale on the wiki already which makes sense since it was already explained that the more chakra you have, the higher your AP becomes as long as you're able to control them very well. So Hinata being able to control such a large amount of chakra and refilling BSM Naruto without facing any sort or form of exhaustion should scale her to BSM Naruto in AP.
Just recently I asked KT what he thought about
"Naruto claiming nobody in the village would want to mess with Hinata due to her strength as a shinobi" I asked if it could be served as the main argument while Hinata with Hamura's amp upgrade would be a supporting argument. But LordTracer replied by disagreein with the proposal because he thought it only serves as a supporting argument at best. I disagree with that notion because characters in this wiki already got upgrades specifically from statements alone.
Kabuto
Kabuto got upgraded to town level merely just by a statement made by Jiraiya and Orochimaru. It was considered to be enough for a main evidence.
Eida
Attack Potency: Unknown, possibly at least Planet level, likely Large Planet level (Stated to be one of several cyborgs that greatly surpassed Jigen's power)
Another character that virtually has no combat feat at all yet was upgraded to 5-B based on a statement even after she claims she isn't really much of a fighter you should depend on physically. Although, I do agree she's stronger than Jigen even without hax, there is no supporting evidence for her here. This is why she is given the "possible" and "likely" terms which is understandable.
Sakura
Attack Potency: Large Mountain level+with the Strength of a Hundred Seal (Hashirama Senju stated that her strength might be greater than Tsunade’s, and she doesn’t have to waste any chakra on maintaining a youthful appearance like Tsunade does[23]. Stated to have the strength of Tsunade[24]. 100H Sakura, KCM Naruto and EMS Sasuke were all portrayed as being comparable to each other[23][25][26][27])
Once again, another character is upgraded purely by statements made by Hashirama and the databook. They were also considered as main pieces of evidence to upgrade Sakura to Naruto and Sasuke's level. Once again, I'm not arguing that it shouldn't be used, but if it can be used for a specific character, then it should apply to other characters as well.
Boruto
City Block level: (Even as a ninja academy student, Boruto was hailed by his peers and even teachers to be an incredibly skilled shinobi for his age, with Kakashi Hatake comparing Boruto's skill to that of a Chunin despite the latter not even being a Genin
This statement is almost identical to Naruto's statement of claiming Hinata shouldn't be messed with by anyone on the village. Both Boruto and Hinata in these cases were considered "strong/skillful" enough to not get messed with by anyone in their respective comparisons. This statement is the only reason why pre-academy Boruto is the only kid in his generation to have a tier.
So if a statement is enough to make a tier upgrade for Boruto, Sakura, Hashirama, etc, then there is no reason why it shouldn't be enough for Hinata especially when she still has a piece of supporting evidence with Hamura's chakra upgrade. My justification for Hinata's upgrade still remains the same;
Attack Potency: Small Planet Level+, possibly
Planet Level (
Naruto claims that based on Hinata's strength, no one in the village would dare mess with her, indicating her relativity to anybody from the village which would include
Naruto and
Sasuke). After receiving a massive chakra amp from Hamura,
Hinata's chakra reserves drastically improved in size and potency till the point she completely replenished Bijju Sage Mode Naruto's chakra reserves after it got absorbed by Toneri. Hyuga members are able to increase their AP drastically after getting a chakra boost from a source as seen in the war arc where Hinata went from
producing little power with her air palm, to
deflecting the arm of the ten tails usign the same jutsu but with a kyubi chakra amp. This means Hinata with Hamura's chakra possesses attack potency on the level of Bijju Sage mode Naruto.
