But also, as others have pointed out, in TOS there was very little rhyme or reason to the Stardates, and SNW seems to have embraced that. It’s actually seems to be less non-sequential this season than in the first.
My personal headcanon is that after the Klingon, Starfleet implemented a sort of two factor authentication to the stardates so they’re somewhat randomized, and can’t be properly pieced together with the proper “key” that lets you know the actual sequence of events.
