At Joshustu:
Good point, however the point I was trying to make is that if chakra control allows a user to be more precise I don't see why regeneration is considered to be the pinnacle. How is regeneration (manipulation of cells) being more precise than genjustu or other very precise techniques like gentle fist, cell sized bombs or other similar techniques. I don't see why tsunade is praised for having good chakra control allowing her to heal, and yet other characters do thing on similar levels of precision and arenot known for good chackra control....
The only reason I can think of is related to your last point, that chakra control doesnot affect precision it is simply being efficient.
If thats the case, then its even less special..... than allowing for precision...because all it allows you to do is more with less chakra. If thats the case, then naruto ( using enough chakra) should be able to do everything tsunade or sakura does ( unless you believe sakura has enough control to compensate for the difference in chakra capacities between her and naruto).
If we assume chakra control + chakra capacity =justu than someone with less control but more chakra can do the same thing as someone with more control, which doensot make any sense because that hasnot been shown in the manga.
Regeneration is not at the pinacle of chakra control, being able to form the seal is.
Seal =/= medical ninjutsu.
Tsunade just chose to use it to aid her in medical ninjutsu (byakugou creation rebirth and remote healing) It's basically just a chakra container you can do with what you want.
Instant regeneration is considered to be the pinacle of
medical ninjutsu not chakra control, i understand if you would mistake the two.
Efficiency of using jutsu and precision is pretty much the same thing, just two different words to address it. It chakra control wasn't special it would not be held in such high regard.
Someone with large chakra reserves cannot do everything someone who is great with chakra control can do. For example the same tree climbing excercise.
Another example, Naruto is more than capable of getting a byakugou seal if it was solely about chakra reserves, however he doesnt show the discipline to be able to focus his chakra in that one spot, in such a way required to form the seal. You have to do this while you eat, sleep, fight you name it until the seal forms.
Huge chakra pool only benefits in that it makes up for sucky chakra control and you wont have to worry about exhausting your chakra basically.
People with lesser chakra pools cannot compensate for it with good chakra control in a case of Sakura (good reserves) to naruto (monster reserves)
However that same good chakra control may allow them to do something that would seem to need alot of chakra to perform on the others part.
Example ninja with average chakra reserve + poor chakra control = not able to do something that may require decent chakra reserve.
ninja with average chakra reserves + good chakra control = would probably be able to pull it off.
ninja with huge chakra reserves + poor chakra control = can do it with wasted chakra but would not matter.
That's basically it.
@bold : It does make sense, If Naruto makes a shadow clone and uses III amount of chakra to perform it.
Sakura could execute the same thing but only use II amount of chakra.
In summary same jutsu less chakra used.
