I don’t think counting by days is quite accurate—how much content is in a day varies a lot, not only because earlier days are shorter, but also because of things like that stretch in Grifter’s route where basically nothing happens for half a week.
Yikes, I was already not looking forward to Grifter's route. It seems kinda like a token trait for him to have depression, although, I suppose I cannot speak since I don't deal with depressive mood disorder. He's great for all the chub-lovers though.
To be fair, it happens fairly early, and there is a lot of actual content in Grifter’s route after that. I’m not sure exactly how much is in each one, but it doesn’t feel like any of them are getting particularly shortchanged.
