That is pretty amazing. I wonder if it's purely a matter of training, or if there's some neurological quirk involved.
Hmm. A nerve impulse travels at ~40 mph. The pellet travels at ~200. The pellet has to cover what, 50 feet? While the nerve impulses have to travel perhaps 5. But then muscles have to contract, and the sword has to move just so...
What's most impressive to me is the coordination this takes. He has to notice the gun firing, judge the pellet's trajectory
correctly, and get the sword in place to deflect it. That is a very complex action to perform without consciously thinking about it.
(Assuming for the moment that he does not consciously think tenfold faster than a normal human. Which sounds unlikely, but I suppose isn't out of the question. I mean, if Ramanujan could calculate arbitrary cube roots between words...)
But yeah. Seriously. Wow.
