I think it's understandable that Asuna's favorability rating limit towards Kirito is 999, while towards Inoda it's only 400. For Asuna, Kirito is her lover, while Inoda is just a friend. Unless some key events happen, her favorability rating towards Inoda can't go beyond the range of friendship.
Also, I noticed that all of Asuna's data in 12.gif is in gray. Does that mean that these data are not real, or at least not the latest data? Maybe in the game, since we play as Kirito, we can't directly know Asuna's current status, and what we know might be wrong or outdated. Players need to do something to get to know Asuna's actual situation.
