Sharingan and MS are 2 seperate forms. Base Sharingan means the 3 Tomoe version. MS and base Sharingan arw not the same thing. Check your terminology.

Sharingan can only predict movement within its field of vision, this is why Sasuke successfully dodge A and hit him with the Chidori. It just didnt do any significant damage. From this point A's arm was out of Sasuke's FOV. No matter what Sasuke didnt have full view of what A was doing. The Sharingan did everything it was supposed to do in this situation.

You debunked nothing. Go read the manga.
