You missed Present day: Characters in our present, story takes place in the present, but with technology involved that is beyond our present technology (examples, Men in Black, Torchwood, James Bond (pre-Craig) movies, Doc Savage, Johnny Quest).
Other than that, pretty good breakdown, though it seems to assume time travel in your scenarios. I'd say most sci-fi is either stories that take place in the present, with present-day characters, or in the future, with future characters... time travel is a common trope, but not predominant.
