2-3 Look OLL(avg12) vs. 1 Look OLL(avg12)

[Lt-UnReaL]

This shows how much time learning OLL saves (for me, at least), minus the 7 easy ones with all 4 edges oriented. So if anyone is deciding to learn all OLL, maybe you would want to look at these times to get an idea of how much it saves.

2-3 Look OLL:
Average: 18.89
Times: 19.98, (24.36), 18.02, 18.87, 20.84, 18.64, (16.08), 18.83, 18.20, 18.74, 20.23, 16.56

1 Look OLL:
Average: 16.98
Times: (12.98), (20.00), 14.81, 19.19, 15.94, 15.94, 16.78, 18.77, 16.30, 18.34, 17.98, 15.75

So yeah, around 2 seconds.

What do you mean by 2-3 Look OLL?
This kinda firms up my belief that full 2-look doesn't give that much over 3LLL. Probably would be better if more people did this, and with more trials though.

What do you mean by 2-3 Look OLL?

2 Look OLL is not true 2 Look. Occasionally you get the case when no edges are oriented, or the "dot" case. That requires 3 looks.

 

[hawkmp4]

Not really. When I get no edges oriented I do F R U R' U' F' f R U R' U' f'. That's one algorithm. I don't have to look in the middle of that.

Not really. When I get no edges oriented I do F R U R' U' F' f R U R' U' f'. That's one algorithm. I don't have to look in the middle of that.

Very good point. I didn't think of that.

The dot case is why I learned only the OLLs with all edges/zero edges permuted. Means I have a true 2 look last layer (except the 10-15 easy cases I know)

If you plan on not learning all the OLLs, at the minimum most people would recommend learning at least those 7 extra. They aren't that hard (3 of them are just doing your old alg from the correct angle to utilize it).

 

[hdskull]

Yea, something like that, about 1.5 seconds or so for me, when I practiced the 3x3.

This reminds me that I STILL have to finish learning OLLs -__-.

Very good point. I didn't think of that.

That is just FRUR'U'F' + FURU'R'F'(from a different angle), so I'd still say that is 3 look. Most people just do FURU'R'F' + U + FRUR'U'F' or some variation of that when they have no edges oriented, which is basically not looking in between. (I'd still count it as 3 look, though.)

So how would you solve the OLL case that F R U R' U' F' f R U R' U' f' solves? Probably the same algorithm. Or the same length, at least.

I don't quite understand what you mean. :x For that case I would do y2 M' U M U2 M' U M. I don't think that is what you meant, though, is it?

 

[hawkmp4]

No, I meant for http://cube.garron.us/tools/algsolve.php?alg=F+R+U+R'+U'+F'+f+R+U+R'+U'+f' that case. But either way- you look at it and immediately know how to solve it, yeah? I can orient the edges in that case after looking at it once. That's one look.

Oh, I see what you mean. That's one case, though. There are 6 other cases with no edges oriented.

The way I learned oll is I first learned 2look oll, but the algorithm for the dot is pretty long and time wasting. So after I learned all 7 corner oll algorithms, I learned the "no edge oriented correctly" algorithms, then it was way easier.
