P is better than Q not because Q’s initial five defections, but because it plays more than half of the match like TfT. So it’s basically only a 43% CliqueBot. The problem with CliqueBots (under rules of this game) aren’t resources spent testing the opponent’s identity, but that they are cooperating neither with the nice strategies nor with CliqueBots of other types.
