I'm fully aware there are 52 weeks in a year. Paramount themselves have said they want 50 weeks of trek. So again, it has nothing to do with which show is or isnt the flagship and all about how paramount is choosing to schedule the shows.There's 52 weeks per year, not 50, so it's not like a round number of 5 series will get you there. And there's no particular reason to presume that CBS wants to have each of the shows appear like clockwork the same week of the year. A few more weeks of Discovery just means everything else is pushed back by a few weeks.
I am really confused TBH by the overlaps happening this year. I can only presume they didn't want to have to push back Picard more than a few weeks.
