Luck can and does play a role. The official regulations for scrambling do require an optimum solution of >x moves. It doesn't take into account solving technique though as that's not really feasible. A scramble might be considered really lucky for a roux solver and unlucky for a cfop solver. It may even be lucky for a cfop solver that builds a white cross but not one that builds a green cross. There are far too many variables to take into account. Especially since one of the biggest sources of luck when using cfop is OLL skips (1/216 chance) and PLL skips (1/72 chance). An OLL+PLL skip would be insane but far too rare for competition. OLL and PLL are the O and P in cfop so occur at the end of the solve so they are pretty much impossible to predict since there are so many possible ways to do the cf (cross and f2l) portions of the solve. Even if you don't get a skip, some OLLs and PLLs are faster than others. A "u perm" is way better than a "g perm" for PLL. In the OLL step a sune is really fast. |
