Talked with SomebodyData and they said you might be able to help me with this calc. I'd do it myself, but between two jobs and other stuff, I just can't make the time.
If I remember correctly, you did a calc for that as well, but it was dismissed as aim dodging. This time however is different. The feat in question is the moment when Fanatio dodges her own light beam that was reflected by Kirito, and she does so after it was reflected. I have the math set up here[], but don't have the time to collect the necessary information to do the calc.
I was curious if I might be able to request you. I think this calc could be very important for bumping up the speed of characters from the earlier Alicization arcs, as Fanatio scales to many other Integrity Knights, and Eugeo even states that her reflexes seemed to be about on par with Kirito's, who is relatively equal to Eugeo.
Posting here since there's apparently a problem with my login session, but Iron Man reaching Earth that fast would be consistient with Graviton throwing Iron Man into space in seconds, and Hulk throwing The Leader's radio into space in seconds.
