Ahh, I actually just recently wrote something about this, but I think I made it too cryptic so I should probably rewrite it. In essence, what's helped me recognize a lot of these things and adjust mid-match is typifying certain behaviors. If you're too busy paying attention to other things, it's hard to spare the cognitive power to readjust meaningfully. Take someone's recovery habits for example. Decompose recovery into a few general subsets: stage-hugging, low, high, offensive (baits gimp attempts), etc. If you have these categories pre-loaded into your head, as well as answers thereto, the mental strain is removed trying to assess what's happening at the moment, since you can, in essence, "shift gears" more easily when the gear is already in place and doesn't need to be made mid-match, as it were.
Consider an example in my case outside of Smash in line with the concept of explicit acknowledgment of something. Many years ago I started learning to read music, and for the longest time, I operated on a fairly intuitive level. I didn't make note of things like "notes switch between being between the staff lines and on them every octave," or "the two notes which constitute a perfect 4th are almost never both on a line or outside of a line," which was a useful point of reference so I didn't have to manually reevaluate the spatial relationship between notes every time I looked at sheet music. It made reading much quicker by having those points of references, principles, etc.
Here's the thing in the event I said it better there than here:

Appreciate it, dude!
