For BD mentioned "EVERYONE" will be lewdable, I think there will be new LIs all throughout the game.
But I also expect them to be few and just sprinkled in as it fits the story with tournaments, events and the like, and a lot of the girls don't need to be around the MC all the time - they seem more like fans/groupies, happy about some attention, but no permanent relationships.
For me, it feels like that was more or less what the first week has been for - establishing the basic cast with the more important girls.
With switching the flow to weekly overviews, only showing important tidbits, assuming that there was mundane downtime in between that also the girls had their part in, the big getting to know everyone at the same time should be over.
Doesn't reduce the problem of time going by until you see your favorite again (especially if your favorite is no main girl), but story wise you always have to assume they are involved in the story where you aren't there to see it - unlike during the first days.
