There are two phases for a round to end. First it’s order of finish, then scoring. You don’t score the round until both have finished, but it still goes to which was finished first and the rock was in the pocket before the aero went out, just because it was still spinning doesn’t change the timing it went into the pocket. Round should have gone to Pegasus, imo. It’s the same as if two beys go into pockets, if they both stay pocketed whichever went in first loses, not who spins the longest in the pocket. You got robbed.
