2x2 first layer move count

[Daniel Wu]

How many moves do you take, on average, to solve the first layer on the 2x2? Permuted, like you were going to use CLL.

I'm just curious...

doing an avg of 5 right now, will post my results
EDIT: avg of 5
5, 12, 4, 8, 6
comes out to 7 moves exactly, if you avg it taking out the best and worst counts it comes out to just over 6 moves, so i would say around 6-7 moves on average, i am also including a timed avg of five with just making a layer.

3. (1.53) F R2 F U2 F R' U' R U

5. 2.59 U F' U' F2 R2 F' R2 U2 F'

Usually takes me about 9-14 moves to make the first layer.

Always under 7 for me. Usually 3-6 though.

1. R U' R2 F U' F' U2 F' R
3 moves

2. R2 U2 F R' F2 R F2 R2
8 moves

3. F R2 F U2 F R' U' R U
6 moves

4. U2 R' F R' U' F2 R U R'
9 moves

5. U F' U' F2 R2 F' R2 U2 F'
7 moves

I came out to about 6-7 too.

1. R U' R2 F U' F' U2 F' R
3 moves

My first side would be 3 moves as well. The same 3 you apparently saw. However, that's only because I know EG1. You asked how many moves to "solve the first layer.. like you were going to use CLL." That's not a full layer.

wow, those solutions are MUCH better than mine, especially the second one, although on the third solution i think you mean z2 U2 L2 U L2
thanks a bunch, those should help with my move efficiency

My bad. I scrambled wrong. How long did it take to learn EG1?

How long did it take to learn EG1?

I spent a considerable amount of time looking for good algorithms, so it took me longer than it would have if I was just learning algorithms other people had found. It paid off though, in my 3.06 average of 5, both sub 3s were with EG1.

The upper bound from any scrambled state to the white layer solved is 7 moves, I'm not sure what it is with CN but I'd imagine with CN you can almost always or always do it in 6. My average is 6-7.
