^i understand where you are coming from, the math is convincing (well chakra in itself is not really physic but whatever) :)

as for appetitte: chakra exhaustion =/= calories (this isnt toriko) XD, a ninjas body makes up one part of chakra and surely a healthy body is better than a sick one but chakra-exhaustion never showed to make the users hungry :)

for walking : kakashi mentioned it, at some point unconsciously the shinobi will walk on walls and water whil fighting, i dont think that air would ne amy differet, yeah, it should take a lot more chakra control but at some point it shouldnt be impossible to do it ^_^
