What is this Petrus Last Layer (new meaning for PLL :D )

[BatafCube]

So i was messing around the net and i was looking for some easy ZB cases to learn.Then i remmembered along time ago looking at something at Lars Petrus's site.I went there and found this http://lar5.com/cube/270/index.html

What is this ZBLL?
Lars Petrus invented ZBLL befor Zborowski and Brunchen?

It looks easy so i am thinking of learning it.Tell me please.

I just use standard fridrich oll/pll. Coll/epll should be about the same speed, and zbll is many, many algs, and you shouldn't start with that.

 

[Cyrus C.]

It's just a different way of 2-looking the last layer, except you have more skips & more algorithms.

 

[4Chan]

That system is similar to COLL, with outdated edge cycle algorithms.

Noobs on youtube like to tell me thats a "complete ZBLL list" >=/

It's also completely biased, making his method sound better than it seems.
One look, 2 algs, means that you use ZBLL recognition to recognize the case, and solve with 2 algorithms.
First of all, ZBLL lacks that limit, and accomplishes last layer in much less turns.

He's never learned the ZB method, and ZBLL is superior to his 2 algorithm system by far.


TL;DR, It's COLL+EPLL

I actually think it is a very good alternative for those who don't want to learn the big list of ZBLL algorithms. One doesn't have to use Lars' exact algorithms to implement the system either or could mix it with OLL and PLL. Many cubers implement a similar idea with a two look OLL (i.e. orient edges, and know what OCLL case will come up when you finish the edges). However, I do believe with that many cases it would still take quite some time to master.

 

[JLarsen]

Compound last layer? Like compound oll? Interesting...the benefit seems meager though.

 

[4Chan]

ZBLL isn't hard to memorize. After a while, the big list doesn't seem big at all.
The critics seem to like to play up that fact.

ZBLL can be put into muscle memory in a matter of months. d:

On a relevant note; how is COLL better with Petrus than OLL PLL? I understand it's better than COLL with Fridrich, but compared to OLL PLL with Petrus, I see no advantage.

Well apparently adding .5 of a sec for recognition and .5 of a sec for execution of COLL over OCLL and saving .5 of a sec on EPLL makes sense.

EDIT: Whenever I use COLL I fail, and I know most of it. It might be because of my not so great EPLL, but it definitely isn't because of my recognition.

 

[4Chan]

Likewise, I think it's the same.

When i use COLL i win, and i have 2 more edges to worry about then you do...

 

[Inf3rn0]

The idea is to learn only a reasonably small number of algorithms - certainly less than the 78 needed for Friedrich, and for each of the 270 distinct positions

Well i began giving it a quick read and got to that sentence. I was quite disapointed.

uhh, you use CMLL...

Same recog, and I think like 20 of my CMLL algs are COLL's.

Well, it does use COLL algs, and you are free to use other algs too.

Care to explain why you don't consider it a complete ZBLL list? As far as I can tell he gives a turn sequence to solve any LL case where the edges are all flipped correctly.

It's also completely biased, making his method sound better than it seems.
One look, 2 algs, means that you use ZBLL recognition to recognize the case, and solve with 2 algorithms.

Well, it's more like just one algorithm, but instead of memorizing it in "trigger chunks" you memorize it "alg chunks".

First of all, ZBLL lacks that limit, and accomplishes last layer in much less turns.

What limit? Lars claims 14-15 move count, which can probably be brought down a bit by learning algs for the 18-20 move cases (I counted to 24 of those cases (I didn't count PLL), and some of those are inverses of eachother).

He's never learned the ZB method, and ZBLL is superior to his 2 algorithm system by far.

Before saying that lets wait until these things are actually tested.

TL;DR, It's COLL+EPLL

No, it's not. Ok, some cases are solved like that, most are done as two short COLL algs.

 

[BatafCube]

Are ZBLL algs very hard to learn?

Well of course, I just think it's a completely pointless addition to the thread when you use Roux.

On-topic: Irontwig, Chris knows ZBLL, so maybe if you want to test out which is better you should learn Petrus' LL

I am thinking to be a rebel and learn PSLL (Petrus'S Last Layer)

But does that mean i have to learn his COLL? - http://www.lar5.com/cube/yMain.html
