Raising up and swinging a sword before a guy can cross 100 meters sounds hilariously unimpressive my guyView attachment 840
Step 1: Raise sword (done so can fire Excalibur)
Step 2: Swing
This means Artoria is fast enough to use it before using Iskandar cross 100 meters. Even if you say couple of meters is not 100 meters, there is nothing contradicting to what is stated.
@shiny I end up having to argue for you now.
At any rate even basic logic is not comprehensible to TheWorld.
