You're very thorough Carol-Rose! Nice of you to take the time.
I use what I imagine is a variation of the screenplay trick. Or, I try to use it. I think readers only need to know enough to get them through the scene. So, if they don't need it for that particular scene to make sense, a lot of the time it can be tossed out. Of course, that doesn't fit every circumstance. Often they'll need things for future scenes.
I like exposition in sci-fi. I think how curious a reader is in general plays into how much exposition they're willing to read. If you engage my curiosity, I'm a lot more forgiving.
