I doubt that, since he made about 26% in 3 months, i would say he needs about 9 more months for the other 75% So i would probably guess, we get another update December/January.
I cant tell for sure, but so far as im aware, its just for your personal notice to see how well you are doing, As long as its not greyed out, you are not missing out on anything.
Im beeing totally honest with you, im a decently fast reader, and this game took me about, not gonna lie, 17-18 hours? to finish it to the point of 0.8, you can have +/- a few hours, depending if u fail routes or skip site scenes etc.
But overall, you will have quite a while to play :)
