While doubles wins are technically giving rank 1, 2, & 3 grimoire score boosts for 25, 50, & 100 wins, respectively, from some point after TTK was released, the grimoire card, at least for those who attained it in Y1, does not have rank rings on it. Moreover, in Y1, doubles wins did not contribute to grimoire score. Unless a patch has notes indicating that the current behavior is supposed to happen, I would expect this to be treated as a bug. In such a case, I would expect everyone's grimoire scores to be properly recalculated and for 4780 to again be the absolute maximum score. Furthermore, if this grimoire score award for win ranks is the intended behavior for the doubles grimoire card, then the grimoire card has a bug regarding win rank rings not displaying, at least for anyone who obtained the card prior to Y2. In this case, I would expect to see a properly retooled grimoire card take the place of the current card and 4795 would be the legitimate maximum grimoire score.
