"Yeah so...?" It means I'm right and you're wrong.
WTF are you talking about? This guy is crazy.
How does that prove you are right and I am wrong? Are you alright in the head? Stop kidding yourself, you havn't won every debate you have had. You cant even understand the simplest of things. Listen closely ok?
1. Viz translations, it is confirmed that Minato has reflexes comparable to V1 Raiakge. Fact.
2. There are many factors which are included in dodging a punch (such as distance between you, the length of their arm etc). Which means that dodging a punch/object does not prove you have faster reactions than it. Fact.
3. In this situation, reflexes is the dominant factor in dodging the attack from that distance. Because of how small Amaterasu is, you don't need to move that far to dodge it so speed is really that dependent. Therefore if you don't have the required reflex, you won't be able to dodge it. Fact.
