7x7x7 multi-BLD: DNF (0/2, 3:39:43.95, 1:50:00 memorization)
Well, I finally tried it. And it wasn't a bad attempt, I guess. The first cube was off by just 6 pieces: 3 centrals and 3 inner + centers. The second one was off by 23 pieces: 3 centrals, 4 inner wings, 6 obliques, 3 inner +, and 7 inner X centers.
I made so many silly errors along the way. I actually solved all the corners on the first cube completely before I realized I was using the wrong cube's memorization. I had to undo all the corners and then do them the right way. Amazingly, I got all the corners right! Then when I started doing the inner X centers, I forgot I was supposed to do inner X and did outer X with the inner X memorization for about 10 pieces, then realized I had messed up and had to backtrack them all. I didn't make any mistakes on the outer X or + centers, so obviously I backtracked those correctly as well! And then, at the end of the first cube, I did all the centrals wrong - again I used the memorization from the other cube. And this time I didn't even realize it until I was done with the second cube (I do centrals last; as I was doing them, I realized, "I've already done all of these - I remember doing them before!"). So I put the second cube down and grabbed the first one again, and then undid all the centrals and redid them with the correct memorization. I got centrals wrong on both cubes, but obviously I got close on it.
I was just too tired to do a post-mortem when I was done, so I really don't know where my mistakes were. But I did learn the importance of really getting straight what order to do things, so I won't make the mistake of applying the wrong memorization. Hopefully I'll do better with that next time. (Proof that I'm certifiable - I actually used the words "next time". Please don't have me committed!
