Wow, these algs are consistently faster than R’ T perm R2 for me. Plus it saves you from doing an awkward D move (if you get it from the front or back angle). This is the first time I’ve come across these algs, although I’m sure they’ve been shared somewhere before. I’m kinda surprised that these aren’t commonly known and shared in tutorials though.

Instead of T perm I use J perm but same idea. But the D move is always awkward.

I noticed you can also leave the R2 F2 R2 or R2 B2 R2 at the end too. This gives another case:

layer on top, bar on right: R2 U' R2 U R2 U' R2 U F2 R2

You can also swap U and U' in the PBL algs. I tried experimenting with putting the R2 F2 R2 in different parts of the alg. Idk any good alg for bar on left. Here's experiments

F2 R2 U' R2 U R2 U' F2 U R2

Obviously you can just mirror the bar on right alg as L2 U L2 U' L2 U L2 U' F2 L2 if you're good at L moves. I guess you could do
z U2 R U2 R' U2 R U2 R' F2 U2 but that just seems stupid.

I think the reason no one cares about these algs is because everyone moves on from Ortega to CLL where you always have a completed layer on bottom.

That's a cool idea. You could also just do algs for T perm on D (R2 U' R' U L' U2 R U' R' U2 (x')), so just choose the faster one.

I don't get what this alg is doing

 

[PapaSmurf]

It does a T perm on D.

 

[qwr]

It does a T perm on D.

wouldn't that involve D moves? or were those translated into equivalent U moves? Idk I didn't check

 

[Deleted member 55877]

I think the optimal "T Perm" alg for 2x2 is R' F R F' R U2' R' U R U2 R', this can be modified to be done on the D layer by making the first and last R' moves to R moves

Do the alg then see what it does. It swaps 2 adjacent corners on the D layer.

I think that the alg I posted (or maybe qwr's) are better.

Ik what it does I just don't see the T perm I know anywhere

Why are my fingers so slow Maybe I should use my magnetic cubes

 

[PapaSmurf]

Switching to a magnetic cube didn't help for the first sub 2 average. If the problem is your TPS, unless your hardware sucks, you just have to practice. Drill algs and keep on drilling and solving.

well I switch what cube I use every session (little magic / chuwen / xinghen / valk)
is that bad for muscle memory? I assume so. I think I got better times when I stuck with one cube for a few sessions. I average nearly about 6.1 with little magic and 6.5 with chuwen.

 

[PapaSmurf]

It's not bad for muscle memory, although it might be bad for your turning, as if you're used to one cube you can adapt to the finer details of how it works.

 

[qwr]

idk I just can't turn as well on some 2x2s. I haven't figured out why yet. I think it's because I'm used to the speed of my little magic 2x2.

Here are Kociemba's 2x2 solver move optimal algs (no AUF) and my current alg. Basically the move optimal ones kinda suck.

Opp adj cases: move optimal algs all kinda awkward to fingertrick.

Case	My current alg	Move optimal alg
bar bottom left	R2 U' R2 U R2 U' R2 U R2	F R' U F2 U' R F'
bar bottom back	R D' R B2 R' D R'	R U' F U2 F' U R'
bar bottom right	D R D' R B2 R' D R'	F U' R F2 R' F R'
bar bottom front	R' D R' F2 R D' R	R U' F U2 F' U R'

Adj cases in bottom layer: (there's a lot of possibilities) interesting but idk if I would use them.

Case	My current alg?	good? move optimal alg
bar bottom left	(J perm starting with R') R2 OR F2 R2 U' R2 U R2 U' F2 U R2	R2 U R U' R F2 R' U R F2 R2 U' R' U R' F2 R F' R' F2
bar bottom back	R2 B2 U' R2 U R2 U' R2 U R2	too lazy to find one
bar bottom right	R2 U' R2 U R2 U' R2 U F2 R2	too lazy to find one
bar bottom front	R2 F2 U' R2 U R2 U' R2 U R2	too lazy to find one

full list of move optimal algs you can try if you're bored (lots of crappy ones)

Is there a solver that can assign weights to moves? R and U moves get lowest weight and all other moves get higher weight. It would be even better if certain triggers get lower weight than the sum of their moves.

are you sure 1. is written correctly? I couldn't figure out how to do it
These are nice solutions. I guess I should've asked for how to make layers for CLL

 

[Findnf]

Hi!! i made this. club to talk about the best methods cubes and your sloves And pbs

 

[Couber]

i use ortega and my pb is 1,21

 

[qwr]

ortega, sometimes lbl to practice layer
I used to avg about 6 but now it's around 6.5 because I've gotten lazy
