I never said physical speed, I said reaction speed and in the manga panels shown Sasuke is a blurry spec to Itachi. I literally just went back and looked at the panels. Itachi was reacting to the change in light around him as Kirin was being summoned the entire area got brigher, and it was brightest right when Sasuke throw his hand down and Kirin struck Itachi at 1/1000th of a second. Itachi was already just about blind at the time, so this is a pure reaction feat on his end.
