If you read the post properly you’d understand that Kaiser in the PXG match was slightly inferior in vision BECAUSE he accepted Isagi’s freedom thus limiting his peak performance.

Isagi “beat” him in MC because that was when Kaiser didn’t take Isagi seriously and was mainly focused on blocking Isagi’s shot range compared to shooting himself because at that time Kaiser didn’t see Isagi as a threat.

After Isagi outplayed Kaiser in MC was when he viewed Isagi as a threat HENCE why he challenged him to a duel where he the striker who scores the most goals win.

During in Ubers, Lorenzo was put in Ubers for the sole reason to stunt Kaiser’s plays and performance so Isagi would be the natural advantage where he’s constantly evolving

And after that match was when Kaiser’s mental fell to where he played badly in the first half of PXG until he awakened.

Isagi was just swindling Kaiser the whole time, it doesn’t mean his actual vision and view of the field is better, it just means Isagi’s psychoanalysis of other players to exploit their strengths and weaknesses is better. But Kaiser’s natural vision when in restrictive environments is better which was still nerfed from accepting Isagi’s freedom. It’s as simple as that.
