Some examples of methods that people use to get sub-1 are:
free-3-cycle
M2 edges / Old Pochmann corners
M2 / R2 (I assume this is the case, but can someone verify?)
TuRBo
BH
DIADEM is also a great edges method that would help you achieve sub-1 potential

What memory methods are most commonly used to acheive sub-1 with M2/Old Pochmann???

latter pair images as ARon DIsapointed ME or audio loop as AR DI ME also visual memo as Ville do

How do I solve the cycle B -> D -> V on 4x4 BLD centers, using this lettering scheme for corners (or in this case, centers):http://www.speedsolving.com/forum/showthread.php?25582-Standard-Lettering-Scheme-for-Reference ?

i timed myself using m2 old pochmann( with eyes open) and got a time of 1:12:00

How can I get this number down to something like 30 seconds(changing method is an option)

Faster turning. You could also learn BH for corners.

That's a Per Special:
f2 U' r2 U r2 U f2 U' r2 U' r2 U

A = U' r2 U r2 U
B = f2

Do as BAB'A'

Thank you Chris

EDIT: How do I solve B -> O -> D? The tutorial I watched didn't explain these.

If I understand the letters correctly this is: Ubr -> Bdl -> Ufl which is just an 8 mover drop and catch.
If you want move optimal, it's faster to use a cube rotation: y' r' d r U2 r' d' r U2 y

If you don't want to cube rotate, then you can do a non-move-optimal B9 drop and catch alg (which is still fast):
U' r' d2 r U2 r' d2 r U'

Either way just use a drop and catch style 8 mover alg (with or without a canceling setup turn)

Another Question: How do I solve (edges) DF (on the r slice) to DB (on the r slice)? I know how to solve DF to BD, but the 3x3 alg (r' U2 r' U2) won't work. Same with solving DF to UF.

I'm lost, are you referring to 3x3x3? Unless you're pairing wing edges of a 4x4x4 into groups of 2 wings together, you would never speak of the DF or DB edge on 4x4x4. You would have to qualify that with rDF or lDF or rDB or lDB. If you're talking about 3x3x3, it sounds like you already have algs for what you're asking (you mention r' U2 r' U2), but even that looks like a 4x4x4 alg.

Can you clarify a bit for me? I don't quite follow your question.

 

[vcuber13]

i think hes asking how to shoot rDF -> rDB

edit:
try F d R U R' d' R U' R' F' r2 for rFU

DFr -> FUr is either F d RUR' d' RU'R' F' r2 or y' U r U R2 U' r' U R2 U2 y r2, and inverse for BDr

I never asked for DFr -> FUr, to clarify, I'm asking for DFr -> UFr and DFr -> DBr.

 

[vcuber13]

UFr and FUr are the same piece

 

[TheMachanga]

:fp

I realized how to solve it. It's DFr -> DBl, not DBr. My mistake. I know how to solve it now

When do we do backwards commutators (BAB'A')? I watched bldmaster's tutorial but I still don't understand.

A commutator in the form of BAB'A' is just applying the interchange move before the insertion. Depends what you label A and B as.

yeah I know that but when do we do it?

I usually do them when I don't want an extra set-up move.

I use OP for corner and usually I solve it in 40-50 seconds

Now I want to learn an advanced method

Turbo (I know alredy all algoritms) or I have to became to study commutator?
