Mostly going off the fan wiki and interviews - still debating whether (and if so, when) to fit in things like the Deadpool movie.
If it's running more or less parallel (this primarily applies to Netflix series) I tend to fit it in before the corresponding Agents of S.H.I.E.L.D. episodes, not least because I generally prefer the Netflix output to AoS. Plus they're more accessible to me.
