How to sub 25s - 30s?

How about this general guideline:
A perfect alg is optimal (fewest moves), a 2 generator (only R U for example), doesn't use B moves (or D or F moves), has no cube rotations AND uses only quarter turns :)

I have to agree with AvGalen. A good algorithm should consist of only turning the left, right, and upper face of the cube. The down and back faces of the cube tend to take a little regripping (at least for me). The front face is OK.

I always try to have algorithms like this but you won't always get smooth algorithms.

Though it always depends. I do my LL J' perm ((R' U' R B R' U' R U R B' (R2' U R U)) easily sub 2s. Just a invert (or mirror what ever :D) of the regular J. But still I'm with you. Like for all the OLLs/COLLs I'm trying to find algs with just F/U/R moves. Ls are not too bad, I ain't just not so good at them.
 
Wow, this is amazing how so many people are giving me ideas!! One thing that's weird is that everytime new comments come, I have new questions.. lol..

I've heard that after the last pair of F2L, you have to do something to get the OLL to have all the edges?? so Iwould just have to memorizie all the OLL algs. with edges. Does anybody know how to do this??
 
That sounds like ZBF2L. You can learn 16 cases (2 * 8 mirrors) to correctly orient all edges after you have paired the last F2L pair.

Or you can learn the 32 basic cases from cubewhiz.com

Check out this and searh the page for "Orienting LL Edges". That should give you something to continue with :)
 
hm.. pou-pou, i think you might be thinking of something else?? im not sure, but when i checked that site and searched for orienting last layer edges, it gave me the beginners algs.

and.. joey where can i go to find the 16 cases (2 * 8 mirrors)
 
Yes, it's me again trying to find new ways to lower my time.

People talk about like.. 3look last layer 2 look last layer and stuff.. but I don't get it.

Can someone explain to me how does the 2 look last layer work?? or give me an example/site?
 
I use a 4 look last layer. That means that when the first 2 layers are done I have to look at the cube 4 times to be able to solve it (unless I get lucky and skip a step).

When I look for the first time I only try to recognize 1 out of 3 possible cases for the orientation of the edges (look 1) and then my hands perform the moves for that case.

Next step is to recognize 1 out of 7 possible cases for the orientation of the corners (look 2).

Next step is to recognize 1 out of 2 possible cases for the permutation of the corners (look 3).

Final step is to recognize 1 out of 4 possible cases for the permutation of the edges (look 4).



It is also possible to combine the last to steps to form PLL. You would have to recognize 1 out of 21 cases to do that, but it would save you 1 look by doing permutation of corners+edges at once. It would also require less moves.

Another option to combine two steps is to do the first two steps at once (OLL). That would require you to recognize 1 out of 57 cases and save you 1 look and some moves also.
 
I like this thread...

AvGalen, Any tips for orienting the edges for OLL if you do a 4-LLL?

Getting a cross for OLL is probably the slowest part for me.
 
I'm sure you know about FURU'R'F' and FRUR'U'F'. If you have a case where no edges are correctly oriented, then do this alg to make them orient: F R U R' U' S R U R' U' f'
(S=F' f)
 
Getting a cross for OLL is the slowest part for you?????

During the last couple of moves of the F2L you should see the number of correctly oriented edges. This is the most likely thing that will happen:
0: You will end up with 0
1: You will end up with 2. The 2nd one will become correctly oriented during the last 1 or 2 moves so you should be able to see if you get the "small L" or the "line". But 0 edges is likely to happen if the correct edge is on the side that your last move will be (R probably)
2: You will end up with these 2.
3: Same as with 1 edge, but 4 edges is likely to happen if the 3 correct ones are not on the side that your last moves will be (R probably)
4: That's strange, F2L must be done already :)

Orienting 2 edges should be done in 2 seconds, even if you are not a really fast cuber. Orienting 4 edges takes about twice as long for a beginner.

If you want to speed up your OLL, this is what I would do:
First learn these:
0 edges: 1 out of 8 cases
2 edges: 2 out of 42 cases
4 edges: 7 out of 7 cases
then learn these
0 edges: 8 out of 8 cases (low occurence chance, but you eliminate your worst cases)
2 edges: All cases with < 9 moves (high occurence chance, big time-win)
4 edges: You already know them all
Then learn all other 2 edge cases
 
hey arnaud, how do you execute FURU'R'F' and FRUR'U'F' ? what kind of finger tricks do you use ? i still use 2 look OLL most of the time cuz i know 25/57 OLL, but i think i do it those 2 setup moves fairly slow, and my motion seems awkward. it'd be great if u can show me how you do it(w/a video, or with words). thanks
 
Im so close to a sub 30 avg. I took a 12 cube avg ( exclude high and low) yesterday and got 33.14 avg. I can feel it in my fingers. hehe :)
 
I'm sure you know about FURU'R'F' and FRUR'U'F'. If you have a case where no edges are correctly oriented, then do this alg to make them orient: F R U R' U' S R U R' U' f'
(S=F' f)

I know those alg's, I just execute them so slowly :( It just seems so awkward .
