Oh well.
Let x be 300 joules (human level)
Aura Strength is 7200 (24x)
300+7200 = 7500 joules.
300+7200×10 = 72300 Joules, that's close 9.64x
Well, I guess that's fair.
We should still address the efficiency issues and downgrade the character's durability when they use Ryu and Ko
This is what I'm talking about, once a character reaches a certain tier using there aura their physical might becomes negligible.
In order to prove your point that there physical strength plays a larger part then thought, you would have to find an example in which a Character WITHOUT Nen displays power at least comparable to other Nen users.
Once we reach 8-B (Which is what most of the low tiers scale to) their physical power becomes next to nothing compared to what Nen reinforcement makes up for
Currently the strongest non Nen users in the series is Gon with his pillar breaking feat at 6405794.87 Joules.
Baseline 8-B is 46024000000 Joules
46024000000 - 6405794.87 = 46017594200 Joules the VAST majority comes from Nen reinforcement
Physical Power makes up just 0.0139183793% of the total force
So Yes you are technically right about it not being a 10x Multiplier instead it is a 9.998608162x Multiplier for low tier Nen users.
And if you think that Nen itself does not account for all that extra force then by all means PROVE IT.
The burden of proof is on you trying to disprove that Nen reinforcement makes up the majority of a nen attack.
Even ignoring all the evidence against it it all boils down to "I say Nen reinforcement makes up the majority" vs "I say Physical might makes up a significant portion of a nen attack" In which case we turn to Occam's Razor which I believe favors my explanation.
Let's focus on the matter at hand, right?
So, as
@Shmeatywerbenmanjenson accidentally helped me realize is that, Nen efficiency
does play a factor in how efficienct your Ko and Ryu is. Aka,
only Enhancers have access to the 10 times multiplier. Funny.
We need to adapt their profiles to this chart:
Emmiters and Transmuters like Knuckle and Killua respectively would only have an efficiency of 80%, aka, a 8 times multiplier with Ko.
Manipulators and Conjurers like Zushi and Kurapika respectively would only have an efficiency of 60%, aka, a 6 times multiplier with Ko.
It says specialists have an efficiency of 40%, but I don't know if it has ever been confirmed to be the case, and Kurapika's ability seems to outright refute that. Pitou is a specialist but they haven't shown the capability of using Ryu or Ko.
Nope, not the case
More Nen=More opportunity to enhance regardless of efficiencies
I will give an example using Nen users who all have the same size Aura
Human has a base power of 10
All these Nen users have an aura pool of 100,000
A master Enhancer can reinforce to 100,000
A master Emitter can reinforce to 80,000
A master Manipulator can Enhance to 60,000
The Aura amount is still increased by 10 using Ko
100,000 becomes 1,000,000
80,000 becomes 800,000
60,000 becomes 600,000
Your type affinity DOES NOT change the fact that Ko still increase said aura by 10x and since these Nen users have massive Aura pools there Physical attacks make up a mere fraction of there total output.
So it still is basically a 10x (9.99x do to their physical might technically playing a part) increase to AP regardless of Aura type or efficiency for all sufficiently strong Nen users.
It not being a 10x multiplier is only True for the weakest Hunters on the HxH page and since most can't even use Ko in their 9-A keys we don't even need to discuss it.
Furthermore, the use of Ko leaves the body - originally several dozen times weaker than their nen strength - totally unguarded. So we need to figure out if we should divide their durability by 24, or dowscale them. But either way, they should get "lower in most of their body while using Ryu, drastically lower while using Ko"
I agree with this there should be a key for a Nen user using Zetsu in which they scale to the 9-B value all Bottom tier hunters scale to
