 - A6) Stopping the solve:
     - A6a) The competitor releases the puzzle before stopping the solve, and stops the solve by stopping the timer. If a stopwatch is in use, the judge stops the stopwatch as soon as the competitor does this.
     - A6b) The competitor is responsible for stopping the Stackmat timer correctly.
-        - A6b1) If the timer stops before the competitor has solved the puzzle and the timer shows a time strictly below 0.06 seconds, then the attempt is replaced by an extra attempt. A competitor forfeits the right to the additional attempt if the WCA Delegate determines that the timer was stopped deliberately.
-        - A6b2) If the timer stops before the competitor has solved the puzzle and displays a time of 0.06 seconds or higher, then the attempt is disqualified (DNF). Exception: if the competitor can demonstrate that the timer malfunctioned, they may receive an extra attempt, at the discretion of the WCA Delegate.
+        - A6b1) If the timer stops before the competitor has solved the puzzle and the timer shows a time strictly below 0.06 seconds, then the attempt is replaced by an extra attempt. Exception: No extra attempt is required if the WCA Delegate determines that the timer was stopped deliberately, or as a result of interacting with the timer in an unusual way (e.g. making only minimal contact with the timer, not lifting the hands cleanly away from the timer).
+        - A6b2) If the timer stops before the competitor has solved the puzzle and displays a time of 0.06 seconds or higher, then the attempt is disqualified (DNF). Exception: The WCA Delegate may provide an extra attempt if they believe the timer may have malfunctioned and the competitor did not stop the timer deliberately.
     - A6c) The competitor must fully release the puzzle before stopping the timer. Penalty: disqualification of the attempt (DNF). Exception: If no move or any change in alignment has been applied after stopping the timer and before releasing the puzzle, a time penalty (+2 seconds) may be assigned instead, at the discretion of the judge.
     - A6d) The competitor must stop the Stackmat timer using both hands, placed flat on the sensors with palms down. Penalty: time penalty (+2 seconds).
     - A6e) After stopping the timer, the competitor must not touch, apply a move, or make any change in alignment to the puzzle, until the judge has inspected the puzzle.
