Minato being an Edo discredits it since he has 1 arm and is an Edo tensei.
That hardly matters as there's a negligible gap between the reflexes of Alive Minato and Edo Minato, as stated by Tobirama himself. A small gap that would have been easily overcome by the boost being in Sage Mode provides. It is up to you to prove that being an Edo would have dulled Minato's reflexes so badly that he would have been unable to react to V2 A while in Sage Mode.
How can you increase the physical capabilities of a zombie? Minato is dead, the only way that he can increase his strength and speed is by using chakra to enhance it as we know ninjas can do but that leads us to another question. How much chakra does Minato have at that time? He was out of chakra prior to all of that so he wouldn't have that much chakra replenished and no Edo's don't replenish chakra faster, dead bodies don't replenish chakra at all so when they say they have "unlimited chakra" that only means they could replenish chakra as if they were alive.
He had enough chakra to enter Sage Mode, teleport, and use a Rasengan. If he had enough chakra to enter Sage Mode then he had enough chakra to increase his physical capabilities.
Adding natural energy to his chakra would increase the chakra reserve and make it stronger but Minato wouldn't be using it to increase his strength or speed since he didn't think Madara would be able to react to his act.
Except that there's nothing stating that Minato can choose what boosts Sage Mode gives him. That's an assertion entirely made up by you. Simply being in Sage Mode increases Minato's base stats. And as was seen with an Imperfect Sage like Jiraiya, that includes speed and reflexes. Either post evidence that Minato can choose what boosts are bestowed to him once entering Sage Mode or I will disregard it as speculation.
Naruto's reflexes in SM comes from his sensory ability, he sense the danger then reacts to it. I never said Minato didn't have SM sensory ability or that he isn't in Perfect SM, I said he wasn't using it.

. There is no choosing not to use it.
You have to actually use it to use it you know. Tobirama and Minato didn't sense Madara or Naruto's chakra until they were told about the war and they tried to sense them, Tobirama didn't sense Madara in Hashirama's flashback because he wasn't kneading chakra, Minato wasn't using his sensory ability when Naruto lost Yang Kurama and had to be told by Yin Kurama.
Except for the fact that normal sensing is not the same thing as Sage Mode sensing. Sage Mode sensing utilises the natural energy in the environment, making it a passive ability for Sage Mode users. Normal sensing requires some degree of kneading chakra. There's no point in trying to equate the two when they are not activated in the same way, nor are they used to sense the same things.
As I said before, a Zombie can't just get enhancements to their physical capabilities, they have to use chakra to do that as the 3rd Raikage uses his lightning armor to increase his speed. That might sound confusing but I mean going SM won't increase his strength to where he can life heavy objects unless he using chakra to do so. SM Naruto wasn't using his sensory because he didn't expect Madara to use that speed because Madara got his old stats again and his reflexes are tied in with his sensory ability.
SM Naruto still blocked Madara's attack even if he wasn't expecting him to use that level of speed, which heavily implies that he still sensed Madara coming.
You're talking about alive Minato now who has his full stats, Alive Minato>Edo Minato.
But he is not > Edo Minato in Sage Mode. To believe that he is would be to either believe that the base stats of alive Minato far surpass those of Edo Minato, or to believe that Sage Mode only gives a mediocre boost to base stats. The first belief can't be true, as that would be contradicted by what Tobirama says about his own jutsu. The second belief would also be untrue, as it is contradicted by everything that has been said and shown in the manga about Sage Mode.
Gai was moving around launching different attacks, it doesn't matter if you're right in front of a person, you can move side to side and slip their field of vision especially when you have 1 eye
Unless you can post proof that showed Madara was having difficulty dealing with Guy specifically because he only had one eye to keep track of his movements, I will also disregard this as speculation.

. Gai wasn't moving when he was using afternoon tiger and Minato wasn't moving around, he was attacking in one forward motion.
And when you compare both cases, Guy managed to launch his attack (as well as the two others before Hirudora) before Madara could stop it completely and have his arms intact, whereas Sage Mode Minato failed to launch his attack and lost his arm. That clearly shows he struck faster than Minato could.
Minato threw the Kunai around the same time Gaara and Kakashi used their jutsus too but Madara did react to it

That link shows Madara being alerted to the sand wall being erected between him and Obito, and of Minato appearing before him. It does not show Madara reacting to the kunai.
KM and BM Naruto's speed is compared to Minato's FTG speed since all you see is a yellow flash just as you do when Minato uses FTG.
Which has absolutely no bearing on Minato's reflexes.
Tobirama FTG to his kunai which he was using to attack and was knocked out his hand around Madara while Minato's kunai was firmly in the ground. You ask all of these why didn't Minato teleport like this and that but did Tobirama teleport to Obito or Minato who he marked when he was in trouble with Madara? No he didn't.
Because Madara stopped him from controlling his chakra with chakra rods (presumably using Limbo to catch him by surprise off-screen). Tobirama also did not have Sage Mode to help boost his reflexes to the point where he could dodge Madara's attacks, whereas

Edo Minato's reflexes and reactions are lower than when he is alive, SM doesn't increase that, Naruto uses his sensory ability for that but Minato wasn't using that.
Asserting that it doesn't increase his reflexes would be to ignore everything the manga says about Sage Mode. With what the manga says about Sage Mode, Minato should have either teleported out of Madara's way before being countered, dodged his attack and continued through with Rasengan like Naruto did with the Raikage (or like Madara himself did with Tobirama), or jumped out of the way like Kabuto did when faced with Sasuke's Chidori Spear, if he wanted to keep his arm. The mere fact that he did none of these things mean that he couldn't react in time, and if he couldn't react in time Madara would have had to be much faster than V2 A.
Minato cannot Spam FTG, it is a lagg time before he or an FTG user can use the tech. Manga fact.
Where is your proof that Minato can't use FTG multiple times in quick succession?
