SS Competition Results
I'm doing FMC for weekly comp but it always says it doesn't meet the WCA regulations


2nd scramble: R' U' F L2 U' L' B L' U' D' L' F2 L U2 F2 R' D2 F2 D' F2 U B2 R' U' F

Solution: U R U' L' U2 L' U x2 y R U R' F U' F' U2 B' U B R' U' R U F U F' y U2 R U R' U2 F' U F U F U2 F' U2 F U' F' U2 f R U R' U' f' U F' L' U' L U F l' U R' D2 R U' R' D2 R2 B2 (I don't do fmc its just a cfop solve im bad)
 
I can't help much...
BUT
I found this:
  • For 3x3x3 Fewest Moves there is a 1 hour time limit. Provide an explanation in the comments describing how you arrived at your solution.
also, are you allowed to use rotations?

Just to make clear how I feel about this, since this is just an online competition, I would be fine with you changing your answer to have Fw instead of f, etc. and resubmitting your result. This wouldn't be allowed in an official competition, but I will allow it here. Since this is likely the first time you've done it, I am allowing it in the spirit (but admittedly not the letter) of the WCA guideline:
A7g++++) CLARIFICATION A competitor may be considered inexperienced if they are a new competitor, it is their first time competing in a specific event, or they have not competed in a specific event for a significant period of time. The inexperience must be related to the incident.
With WCA regulations, I doubt it would be honored anyway for FMC, since it is considered an event for experienced competitors. But even if it were, the only recourse in an official competition would be to give an extra, and again I doubt that would be allowed for fewest moves.
But under the circumstances, for this online competition, I see no reason not to allow changing the notation so that it is valid and resubmitting.

The specific rules for allowed notation:
12a) Notation for NxNxN Cubes:

12a1) Face Moves (outer slice):
12a1a) Clockwise, 90 degrees: F (front face), B (back face), R (right face), L (left face), U (upper face), D (bottom face).
12a1b) Counter-clockwise, 90 degrees: F', B', R', L', U', D'.
12a1c) 180 degrees: F2, B2, R2, L2, U2, D2.
12a2) Outer Block Moves (outer slice with adjacent inner slices). For each of the moves defined below, n is the total number of slices to move, which must be in the range 1 < n < N (where N is the number of layers in the puzzle). n may also be omitted, for an implicit value of n = 2 slices. Outer Block Moves are:
12a2a) Clockwise, 90 degrees: nFw, nBw, nRw, nLw, nUw, nDw.
12a2b) Counter-clockwise, 90 degrees: nFw', nBw', nRw', nLw', nUw', nDw'.
12a2c) 180 degrees: nFw2, nBw2, nRw2, nLw2, nUw2, nDw2.
12a4) Rotations (entire puzzle):
12a4a) Clockwise, 90 degrees: x (same direction as R or L'), y (same direction as U or D'), z (same direction as F or B').
12a4b) Counter-clockwise, 90 degrees: x' (same direction as R' or L), y' (same direction as U' or D), z' (same direction as F' or B).
12a4c) 180 degrees: x2, y2, z2.
12a5) Outer Block Turn Metric (OBTM) is defined as:
12a5a) Each move of the categories Face Moves and Outer Block Moves is counted as 1 move.
12a5b) Each move of the Rotations category is counted as 0 moves.
12a6) Execution Turn Metric (ETM) is defined as: Each move of the categories Face Moves, Outer Block Moves, and Rotations is counted as 1 move.

and from the guidelines:
E2c4+) CLARIFICATION Examples of symbols or combinations of symbols that are not permitted in solutions for 3x3x3 Fewest Moves: M, e, r, Y (uppercase), T, U1, Ui, U3, U-, R++, R2', R'2, L'w, 1R, 2U, 2f, 2-3r, 1Rw, 3Rw, 2-3Rw, rw, Rr, *, →, ⮐, /, ., ?, [r], [r u], [F], <f>, [f]', [f]2, [x], (x), (L), 2(Rw), (U)2, (U)', (R U)', (R U R'), [R, U], [R: U].
