If so its reasonable to think that any ninja with a large amount of chakra and stamina can do this in which case I can think of a few likely candidates. Its just that Kishi has never really given us any details on how other ninjas rank chakra wise, convenient no?
Even if Kakashi is a low chkara capacity ninja we should be able to assume that the figure he gave Naruto of three times is normal (seems reasonable? Having a third of normal is more than what I would consider low). Then when he said that with the Kyuubi he has one hundred times the chakra it should be obvious the ability to do this scale of training is directly related to the Kyuubi.

I'll add to the motion of this being a great episode, even with the action to keep the ADD kiddies busy.
