how to improve ocll for beginners: 5 techniques movecount analysis

[Deleted member 36445]

As you might know, I like to study and develop new ways to teach beginners to solve the cube easily.

I decided to analyse the movecount of 5 ways to solve the OCLL. they are:

1) sexy move
put the last layer corners on bottom with x2 move and solve the corners with 6x sexy moves. optionaly you can make a z rotation and solve with 6x inverse sexy move

2) sexy move and inverse
put the last layer corners on bottom with x2 move and solve the corners with sexy move and it's inverse. can be solved with less moves than 1 sexy move. again you can rotate with a z move

3) 1 sune
use sune 2 to 3 times to solve the orientation

4) sune / antisune
use 1 sune and 1 antisune max to solve the orientation

5) direct solving
use ocll

1 sexy move:
need for one rotation (x2 or z) and a sexy trigger
sune, bowtie, headlights and chameleon are ok with this method, but antisune, pi and h take 50ish moves to solve, what's terrible, so you might want to learn the inverse right away to drop your times greatly

sexy and its inverse vs 1 sune:
with one sune, sune (obviously), antisune, pi and h drop very well, but bowtie, headlights and chamelleon may be better solved with sexy and its inverse. also take in mind that with sune there is no need for rotation

sune / antisune:
antisune, bowtie, headlights and chameleon drop moves.
(cancellations ftw)

ocll:
bowtie, headlights, pi, h and chameleon drop moves

maybe this can help you decide what to learn (or teach) next

Back then, I just did sune randomly until I got a "good fish" or a "bad fish" (Sune or antisune)
Pretty much how I teach beginners, do sune randomly until you get lucky

yeah I used to spam sune randomly when I first learned to solve. but knowing what you're doing is less frustrating
imagine you had good cases in the first two layers and then you get a case you have no ideia how to solve then you spam sune for 4 minutes. not good

better method 4:
U: (front Sune) (back Sune) = (R U R' U R U2 R') (R' U' R U' R' U2 R) (13 moves)
T: (front Antisune) (back Antisune) = (R U2 R' U' R U' R') (R' U2 R U R' U R) (13 moves)
L: triple Sune/Antisune (15 moves)
H: double Sune/Antisune (11 moves)
pi: (front Sune) (back Antisune) = (R U R' U R U2 R') (R' U2 R U R' U R) (13 moves)

You can always get cancellations and you'll never need to AUF in between.

(I used to do the above U/T/L algs for OCLL until at some point I realised I could use the two halves of the E perm algs to solve T and L.)

nice, I added to the main post.

that technique is perfect for COLL

I learned it that way too except I didn't call it fish.

nice, I added to the main post.

I use sune into antisune for U permuted coll

Heads up: L/bowtie is still 15 moves with triple Sune, not 13 moves.

I corrected. thanks for verifying
EDIT: new table with movecount differences between techniques

 

[Cubing Forever]

the best OCLL technique is of course OCLL but if you're lazy then sune/antisune is the way to go
