Actually no. An M slice away from solved is a DNF because the regulations count an M slice as two moves. Here are the relevant parts of the regulations:

  • 10e1) For each two adjacent parts (e.g. two parallel, adjacent slices of a cube) of the puzzle that are misaligned more than the limit described in Regulation 10f, the puzzle is considered to require one additional move to solve (see "Outer Block Turn Metric" in Article 12).

  • 10e3) If one move is required, the puzzle is be considered solved with a time penalty (+2 seconds).
  • 10e4) If more than one move is required, the puzzle is considered unsolved (DNF).

  • 12a1) Face Moves:
    • 12a1a) Clockwise, 90 degrees: F (front face), B (back face), R (right face), L (left face), U (upper face), D (bottom face).
    • 12a1b) Anti-clockwise, 90 degrees: F', B', R', L', U', D'.
    • 12a1c) 180 degrees: F2, B2, R2, L2, U2, D2.
  • 12a2) Outer Block Moves (outer slice plus adjacent inner slices; n is defined as total number of slices to move; n may be omitted for two slices):
    • 12a2a) Clockwise, 90 degrees: nFw, nBw, nRw, nLw, nUw, nDw.
    • 12a2b) Anti-clockwise, 90 degrees: nFw', nBw', nRw', nLw', nUw', nDw'.
    • 12a2c) 180 degrees: nFw2, nBw2, nRw2, nLw2, nUw2, nDw2.
  • 12a3) Outer Block Turn Metric (OBTM) is defined as:
    • 12a3a) Each move of the categories Face Moves and Outer Block Moves is counted as 1 move.
those ring a bell. it would be a dnf
 
Is it possible for a cube to "wear out?" My old main, the YueXiao, started getting super loose one day even though my cubes are on pretty tight tensions, and I wiped all the lube out of it, and even tightened it a little more, but the faces were gliding way too much during solves. I have the Valk as my main now and it is starting to do the same thing. Does anyone else get this problem on their cubes? I'd say my Valk has about 7,000-10,000 solves on it.

maybe, everything wears out eventually,
 
what is a force cube?
Force cubes are usually described as a set of cubes. That set could be 6 of one type of speed cube, where each cube is a different color. For example, a set of a white, yellow, orange, red, blue, and green Valk cubes would be called a set of force cubes.
 
Depends on the event. For 3x3, it's probably around 20-25 moves on average. Pretty sure it's more than 19 or 20, because the scrambles aren't optimal since that would take too long to find.

Note that the scrambles aren't just a list of random moves; they are a specific algorithm that leads to a randomly chosen state on the cube, so no scramble is favored over any other one.
