Exactly the difficulty of solving a Rubik’s cube is that it doesn’t respond to heuristics. A cube can be 5 moves from solved and yet look altogether a mess, whereas a cube with all but one corner correct is still some 20 moves away from complete (by the methods I looked up at least).
I don’t know the methods you used, but the only ones I know of have certain “steps” where you can easily tell what step it’s on. For example, by one method, anything that’s five moves away will have all but two sides complete.
