Nope, this battle has shown to be known as analyse battle....Okay, first of all... FTG is one of the fastest tech created by Tobirama which means it is instant due to the fact that it improves both offensive and defensive, and second, Kakashi is not able to touch or do any similar tech to Minato, however in that case Minato has the advantage because Minato can just spam FTG with each kunai which leads to his tactic while Kakashi cannot figure out where he is.... Kakashi is indeed fast and strong when the moment strike, but as for The Yellow Flash can easily makes clones up to 2 or 3, doesn't matter how many.
Remember that Minato only way by using FTG combo is to use his clones against such opponent like Kakashi.
Minato > Kakashi, so deal with it..
