now maybe i have a question about the kyuubi for u

i thought about that minato sealed half of the kyuubi chakra... the spirit and the other half of the kyuubi in naruto , right ?
then i thought about doesnt chakra replenish itself in a body from a ninja ?
so maybe the chakra replenish from the kyuubi to 100% inside of naruto ?
what u say about that ?
any ideas ? or am i completely wrong ?
