What to improve, other than look ahead? (Fridrich)

[Erzz]

I still can't break the 20 second barrier. I know full PLL, 2-look OLL plus a few cases, and use a mostly rotation-less F2L style with partial edge control to avoid dot cases.

My averages tend to be around 23-25 seconds. I was wondering if anything other than my look ahead is slowing me down. Cross, algorithms, PLL recognition, turn speed, anything. I don't know anyone personally who is faster than me, so I turn to speedsolving.

My cube is a modded mf8 Legend. It's the best cube I have. Also have a GuHong, LingYun, Type-E, Alpha I and V (modded), and Rubik's.

Here are my PLL algorithms, plus the time I can execute them in. (Left hand dominant when cubing)

Here are some example solves, with the time for each step written. I didn't drill each step, just did each once. OLL and PLL are combined, so you can see if recognition is a problem. My algs are above so no need to write them.

Average of 5 for those is 19.12, barely sub 20, with no pausing except for PLL recognition.

Any help / opinions are appreciated. I could post a video of an average but the quality would be terrible (iPod touch camera ftl)

Most of your improvement should be from getting faster at F2L. Some of your F2L algs are lol.

 

[Cubenovice]

Sorry I cannot help you but I must say this:

Now THIS is what a "help" post should look like!

 

[jskyler91]

you need better n perms and your a's should be sub 2 seconds, they are like the easiest, make sure that you are doing the D2's with you ring not your whole hand. You g's could be faster as well. Are you a lefty or just lefty during cubing? I use these algs: http://www.youtube.com/user/jammyman3014#p/u/9/fWyjLAiEL9o, you could mirror them to the left hand. This guy can do all of these algs sub 1 second and i nearly have all of the sub 2

Pay attention to the way he fingertricks them as they are key to success

 

[Erzz]

I'm lefty while cubing but not while writing.
I do the D2 with my right ring finger, but flick twice rather than all at once.
I mirrored some of Breandan's algs, U perms and V perm, maybe a few others. I was planning on mirroring the Gs eventually.

I'm not sure which of my F2L algs are bad, other than the L U F U' F' L' F U' F' one.
At parts like F' (L U2 L') F and L' U' (R' U' R) L, sometimes I can make the next case easier by doing a U turn before doing the last F/L.
My B and f turns are pretty fast, for the B's I do a sort of quarter-x' rotation. I find it easier than sledgehammer.

I mean honestly, I was were you are about a month and a half ago or so and I just basically practiced up the ying yang and reworked my regrips/ algs. Plus i started going faster with a little less look ahead, it sped me up to about average of 19 and then other things put me at about 17 which is my current average.

I also know full oll though and i am color neutral which helps....

 

[David1994]

Maybe your cross..(I need to work on that also)Holding me back a bit..

 

[MoRpHiiNe]

From those stats I'd say you need to work on recogniton/pauses as your last layer is taking around 8 seconds avg yet most of the algs take 1-2 seconds for LL.
Also your cross could definitely be better, mine is avg around 4 seconds and I avg around 35 seconds so it should be around 2-3, LL should be 4-6 in my opinion and F2l is great at how it is, I'd expect 8-12 seconds.

 

[Sa967St]

F2l is great at how it is, I'd expect 8-12 seconds.

Uh...

 

[jskyler91]

Uh...

Bump, if you want to be able to average a 3 second cross then you need to be doing f2l in 9 seconds or less and that is if you just want to be barely sub 20. F2l should be closer to 7 if you want to be consistently under sub 20 with your current cross and LL times

 

[RaresB]

You could take a look at cyoubx's video entitled why you're not sub 20 with fridrich. Search it up on YouTube Its pretty good.

Uh what?
Just did a avg 12 of each part of my solve;

Cross: 3.36
F2l: 16.18
OLL: 4.36
PLL: 4.32

I use both 2Look OLL and PLL...

Still my last layer is about half my time of my f2l, my cross being a fifth of it... I don't think a 7-9 sec F2l corresponds with a 3 sec cross... I reckon by the time I'm doing f2l in 7-9 seconds my last layer will easily be 4-5 seconds and cross around 2.

Edit: from what I've seen, the ratio of cross : f2l : oll : pll is regularly around 1:4:1:1

Edit2: Looked back at original post, it looks so weird having so many algs with 'L' in them cause you prefer L moves, they are bad for me =P.
