	9f12c) For Multiple Blindfolded Solving, rankings are assessed based on number of puzzles solved minus the number of puzzles not solved, where a greater difference is better. If the difference is less than 0, the attempt is considered unsolved (DNF). If competitors achieve the same result, rankings shall be assessed based on total time, where the shorter recorded time is better. If competitors achieve the same result and the same time, rankings shall be assessed based on the number of puzzles the competitors failed to solve, where fewer unsolved puzzles is better.

9f14) If in 'Mean of' and 'Average of' rounds competitors have the same average/mean result, then the order in the results for these competitors is based on the best result per competitor, with lower meaning better.	9f14) For "Mean of 3" and "Average of 5" rounds where two or more competitors achieve identical average/mean results, rankings are assessed based on the best result per competitor, where "better" is defined as the shorter time.
9f15) Competitors with the same result in a round finish at the same position.	9f15) Competitors who achieve the same result in a round receive and identical ranking for the round.
9f16) For the Rubik's Cube: Multiple Blindfolded event the order in the results is based on number of puzzles solved minus the number of puzzles not solved (higher is better). If the result is lower than 0, the solve is disqualified. If competitors have the same result, then the order is based on total time (lower is better).
