Hand and arm movements are not the same as bodily movement. When he wants it to be, Itachi's hand movements are imperceivable to even the Sharingan, and even when Summoning: Lightning Flash Blade Creation is used against him his hand and arm movements are still imperceivable to the point he can weave signs in the middle.. which also are still imperceivable. If we are to base the bodily speed on their hand and arm movements then Itachi's speed is off the charts.

Let's consider that Summoning: Lightning Flash Blade Creation does this "The ninja tools are thrown with the actual speed of a flash of lightning, ruining the opponent's outset of the battle, and snatching away the initiative. " Yet Itachi was faster than that altogether making he himself move much faster than even lightning going by this logic.
