^but the amount of chakra is still possible for normal shinobi at least they could do it for some time,

afterall walking on water or on walls never seemed to be of any issue (chakra-wise) no matter how unruly the water was or if the ninja fought in the opposite direction of earth gravitation, 1000 times from something that can not even be sensed after some repeating doesnt seem to be a impossible amount :)
