Nice effort, but no as I already told you. :lol

Extra chakra isn't stored for later use. It goes to waste. That is why chakra control is important to begin with.
And hand signs obviously aren't required to mold chakra, otherwise Rasengan, Bijuu Dama, Hiraishin and every other tech that doesn't require hand signs wouldn't be possible. That and Sasuke has used Chidori and regular Raiton streaming without hand signs.
This also makes no sense. Why must you blatantly lie about how techniques work to get your point across? 1 hand sign doesn't perform multiple instances of the jutsu. Shadow Clones create copies equal to the amount of chakra used. Multi Shadow Clones do the same on a much larger scale. That's ONE instance of the jutsu. Not several.

-Sasuke using Chidori without hand signs prior or at the time of activation despite using Katon w/ hand signs a page before.

-Sasuke doing the same thing as the last scan, which blatantly contradicts what you stated about him using a hand sign to "switch back" to Raiton. There's also at least a dozen more examples I can give you. Hiraishin requires no hand signs whatsoever.
