I thought "The Speed" increased the speed of things he chooses (like say he flicked a rubber ball he would make it go speed of sound by just flicking it and using the speed) etc. I don't really see him moving at the speed of sound but I can see reaction speed being that.
but hey NoN Lelouch is mostly new for me (its seems like Code Geass on steroids)
