You can't have 3 corners incorrectly oriented? R U R' U R U2 R' ? Right? What I meant about the proportion is that for example, if the average number of twisted corners is 6 (which it should be), and you only have to twist two of them, if you normally do two at a time, then you are saving 67% of your CO step for execution, and then saving an additional amount of time by memorizing less. I don't use that BLD method, though, so I'm not sure if this is right. This is based on what I THINK I know. :)

Always even numbers. So, assuming that the probability of one corner being oriented is 1/3, you have 1/9 of probability of having 2 correct corners. The probability of having 4 correct ones is 1/81. For 6 correct corners is 1/729. And for all 8 corners correct is 1/6561. So, the probability of having a case like I had is 1/729. > I don't know what proportion of the solve it saved. People solve the cube BLD differently. I use commutators for solving the CO.
