What the winner’s profile shows
Revolution’s audited victory is consistent with its earlier league-stage position. The engine had already finished first in the official Bullet Derived Stockfish Track rating table with Elo 3745, and it carried that competitive profile into the first knockout match. In this Round-of-16 encounter, the result was not a narrow edge but a clearly separated scoreline, with Revolution finishing 19.0 points ahead over a 100-game sample.
From an interpretative standpoint, this is useful for readers of chess engines ratings lists because it links the knockout result back to a previously audited league surface. Revolution’s match win is therefore not presented here as an isolated number. It is read together with the earlier rating context, the mirrored-opening structure, and the closed audit state of the match itself.
