Super Signal can potentially last forever if Ethan can maintain the absurd concentration to use it constantly, which he definitely CANNOT (3 Minutes at maximum and megahighballing, I'll add that in to his profile). Ethan would only use it short moments: for example, if Deathbolt tries to use his Danmaku, Ethan would activate Super Signal for as long as he can to attempt to dodge all of the hits. Though he could just use Subterra Strike to go underground and evade all of it.

Canonically, Ethan cannot use it in his 8-B key, but he is allowed to use it for this tourney as it doesn't jump tiers by itself, only increases reaction and processing speed. He used it for the rest of the tourney, so he should for the final battle as well anyway.
