I am not exactly sure what is causing a hold up at the moment, but here's my summary of where we are right now.
Despite multiple Calc Group Members commenting here leading to off-topic posts, only DMUA has shared acknowledgement to use the calculation (mid-ball with average distance) to remove Kirito's FTL travel speed (which is happening with or without this calculation anyways) and the calculation suggests Kirito can potentially have Sub-Relativistic as his speed at most, however his exact speed is unknown. So "Unknown, at most Sub-Relativistic" until further information is provided in the next volume.
From what I understand, the "Reaction Speed" is causing an issue. Not sure if we absolutely need a Reaction Speed to commit to a Travel Speed, but earlier in the thread, we have concluded that Kirito is not reacting to any sort of "Light" attack, and the attack he is reacting to acts as a Sniper Rifle. So if we absolutely need a Reaction Speed as well to be able to commit this, the feat is right there. Also, he is not exactly reacting to gunfire, but rather is reacting before a gunfire happens to where it looks like the gun will fire pre-emptively.
Asuna's FTL is to be removed entirely. It is a completely baseless claim. Saying Asuna is comparable to Kirito is completely false, as in reality we have seen time and time again they do not compare as stated above. And on top of this, Kirito is not FTL in the first place, which was the point of this thread.
