Speed up PLL execution

[einstein00]

I've heard some people saying that they can execute most, if not all, PLL algorithms in less than one second. I believe this is inhuman. Here's an example:

The H-perm, one of the easiest and fastest PLL cases, is undoubtedly solved the fastest using a variation of M2 U M2 U2 M2 U M2. Personally, I like M'2 U' M'2 U'2 M'2 U' M'2, executing each M'2 with a double trigger with the right ring and then middle fingers, and the U' and U'2 with the left hand. However, I cannot even get this easy algorithm under one second - at best, I can do 1.2 s. Even if I skip all U moves, performing only (M'2)4, I can get at best 1.03 s. Perhaps I'm just slow. But if I cannot execute one of the fastest PLL algorithms in under 1 second, there's no humanly way anyone can execute most or even all PLL algorithms in under 1 second.

If I'm just missing something really obvious and stupid, please tell me.

When people start cubing they often turn at about 1tps at best. Then over time they get faster. Maybe you haven't reached your peak yet. I'm sure there was a time when the really fast people thought that sub-1 PLLs was beyond them too.

 

[waffle=ijm]

Yep. I can sub-0.6 all my PLLs.

So I'm just making sure, there indeed are people who can sub-1 all PLL's? For a while, I thought that maybe they were just exaggerating or kidding or whatever...

The H-perm M'2 U' M'2 U'2 M'2 U' M'2 is 7 moves long. The E-perm x U R' U' L U R U' L' U R U' L U R' U' L' is 16 moves long, not counting the cube rotation. It's hard to believe that there are people going 16+ tps, about 2.29 times my pace.

I'm not one of those clumsy people who just can't turn well. I have been playing the piano for eight years, so trust me, I know my fingers. My tps isn't getting much better than 7-8 tps. There's no way anyone can do 16+ tps.

waffle, i'm not sure if you're being sarcastic or not. If you're serious, then you're doing 27 tps. I'd like to know what algorithms you use.

Vallence has a video on YouTube where he cycles R U' until Ts complete. It was just about ten seconds. Look at his PLL time attacks too. He's got a sub-30. It is indeed possible. It's all practice.

I use Roux....
There are 4 PLLs
all of them sub-1able :

uh, what? There are 21 PLL algorithms. If he finishes in 30 seconds, he averages 1.43 s per algorithm.

(R U')x63 is 126 moves in 10 seconds. That's 12.6 tps, not near the 16 tps needed for a sub-1 E-perm. Plus, fingertricks don't get much better than (R U')x63.

Ah, ok. That makes much more sense! Perhaps I just understood the claims out of context? Is there anyone who can do all 21 PLLs sub-1?

Morten's E perm: 16 moves in 0.72 seconds = 22 tps

How much pausing between PLLs did you measure?

Sub 1 E perms exist. Just check Youtube.

Edit: or that video that was posted earlier.

 

[EricReese]

What E perm alg is that? Ive been looking for a better F, E and X perm algorithm

 

[einstein00]

Wow. That video... is awesome.

How much pausing between PLLs did you measure?

If he were to get exactly 1 s for each of the 21 algs, he would have a 21 s PLL time attack. Adding the pauses, he got 30 s, or 9 s of pausing. If he has to regrip the cube 20 times in 9 seconds, it's 0.45 s per regrip. Even I can do that.

 

[Zarxrax]

I don't think anyone is sub-1 on every PLL. Even people who manage to get sub-1 on video don't do sub-1 EVERY time.
Sub-2 is definitely possible for all algs though.
Several algs are possible to sub-1. The only one I have managed to get sub-1 so far is my U perm. I got close to sub-1 with H.

My PLL time attack is barely under 2 minutes. This tells me that my turning speed sucks compared to almost everyone.

 

[Cyrus C.]

I know what you're feeling. 2.3 H, 2.3 T. I can only sub-2 my U perms.

The H-perm M'2 U' M'2 U'2 M'2 U' M'2 is 7 moves long. The E-perm x U R' U' L U R U' L' U R U' L U R' U' L' is 16 moves long, not counting the cube rotation. It's hard to believe that there are people going 16+ tps, about 2.29 times my pace.

I don't know of anyone who can sub-1 every PLL. I know Breandan (Vallance) can sub-1 every OLL and every PLL except one N perm. The 9 seconds (well actually nearer 7-8 seconds because people have done 28.xx) 'lost' in PLL time attacks are for, as you say, regrips, and also people don't sub-1 every PLL every time.

You say that you played the piano for eight years...well I played the violin for 13 years before I picked up a cube, and like everybody else, was super slow to start with. Now after a few years I can do RUR'U'*24 in sub 6 = 16+ tps.

So it is perfectly possible that people are as fast as they claim. I mean, just look at Felik's WR solve. It was 8+tps iirc and that's including time to move between algs, lookahead, cube rotate etc.

 

[einstein00]

Ok. I believe you guys, especially after watching (about 5 times!) the video Forte posted. If anyone knows what algorithm that was, I'd like to know too.

 

[Zeat]

LOL? practice
I solve H perm in 0.90

It's a pretty common E perm nowadays. To swap UFR with UBR, and UFL with UBL: x' (R U' R' D) (R U R' D') (R U R' D) (R U' R' D') x
It's just 2 8-move comms. Do Us with right and left index, and all D turns with left ring. The D turns are the difficult part - just pull, push, pull, push with that left ring finger. With practise it becomes very fast

Thank you! It flows much nicer than my other 3 E-perms I've been contemplating

edit: oh i noticed that the last U should be U'.

I am curious how you think that playing piano has anything to do with cubing.
I have played piano for almost 3 years (so, notice, a lot less time than you), and I can turn a cube faster than you.
Practicing piano does not make you better at cubing; practicing cubing makes you better at cubing.
