A bunch of random similarities I found between me and Chris Hardwick:
- we both used to be world-class in a few popular events, but have since stopped being competitive in them;
- we both moved on to less-popular events that we can still get impressive results in;
- we both won the 4x4x4 event at a US Nationals competition (once);
- we both haven't competed since US Nationals 2010;
- we're both very interested in math;
- we are both knowledgeable in cube theory;
- we both invented methods (that other people have learned since then);
- we're both active on this forum, and have a large number of posts.
Wow, very cool!

I thought this was neat:
Rounding to the tenth's place, your pb single is 7.6 times faster than my pb single in the following two events:
- Square-1
- Megaminx

I'll see if I can find more things :)

On a much more random note I felt like being silly.

I did a scrambling average. Basically I started the timer (no inspection) scrambled the cube, stopped the timer, immediately started the timer again, scrambled with the next alg, stopped the timer, rinse and repeat :) I did not verify whether or not I had scrambled correctly, but I made my best effort to scramble correctly.

08.73, 07.71, 09.03, 07.68, 07.86, (09.07), 07.93, 07.95, 09.02, (07.27), 08.25, 08.44 = 8.26

How many "steps"/looks do you use for first layer, I need at least 3 looks wich is still to much as I believe.

I wonder how consistent your movecount is (~24), It's not so difficult to get sub 20 moves.
I do:
cross
4 corners. lol

7.32, 6.89, 6.70, (6.23), 7.78, 7.49, 7.35, 7.20, (8.08), 7.42, 8.00, 6.50 = 7.26

that was fun

"Once you’ve done the edges ... do two CORNERS at a time."
I Never tried to do this. I case of of an oriented but missplaced Corner in the First Layer I could think of doing some fast (recog,exec,moves) commutator. ( [R'D'R,U] an stuff )

Is this the kind of alg you speak of? Or do speek of things like preparing two oriented edges in D and than do M'F2M-things ?

For edges-first, there are a number of algs like that one that may help reduce 'bad' cases, but overall, they should be fairly intuitive and flowy. I tend to do the B corners then the F corners (edges on D).

For corners-first, there are plenty 'bad cases' that my sammich approach doesn't provide optimal solutions for, and so algs (that would become intuitive) would be apt to learn.


I'll fix that mistake on the site today; thanks for pointing it out!

... I used to be addicted to cubing. Now I'm not cuz I have to learn all the OLLs and PLLs............

an someone direct me to the thread that was made specifically for a person to ask for example for a cube that turns well and has very good corner cutting abilities, then another person gives him the cube, sorry for the out of context question.

Here's a really weird way to do a 4-cycle of c/e pairs:
R F R L' B L D L' B' L R' F' R'

And here's a single commutator that performs two twisted corner 2-cycles:
(R' F R) (L' B L) (R' F' R) (L' B' L)
= (l' U l) (r' U r) (l' U' l) (r' U' r)

That one's old...

This one, too: [L B M D L : S] D' (and [L B R L' F L : E] D is the easier version)
It's somewhat the dual idea, cycling four edge/center pairs in a layer rather than four corner/edge pairs. I just added a D-turn to make it cycle corner/edge pairs instead.

Messing with lots of Last pair last layer methods, with EP of 5 edges as the last step (from L2L4)
1. F2L -1 pair.
2. FL corner and orientation of LL corners.
3. Permutation of corners and orientation of edges.
4. EP.

CO seems decent, but I'm just doing in intuitively, the 10-20 algs would make this much nicer.
But the EO + CP, I know a few that I just randomly picked up, these seem decent, but I don't know enough to truly judge.
EP seems to be much better than PLL, longest alg on statue's site is 15 moves.(not just judging on movecount, they're very nice other than this 15 move <RU> alg which I can't find a good grip for)

Thoughts? Anyone care to point out some flaws? :3

found one too by playing around:
