unless you're execution time is sub30 it's not maxed out. evidence - Cornelius.

EDIT: wait why did your 3x3 PB averages in your sig go up?

And I do think it's maxed out (in the sense of, I won't be able to improve it by normal means). Conny just turns faster. I have 48ish or so execution. From a move count/TPS standpoint, I won't be able to get much faster in a shorter time.

I'm using stackmat now. I have the old records in a notepad file. I'm trying to find out causes as to why I fail in comp. Stackmatting is my biggest bet.

Speed wise, would corner comms, or edge comms speed my times up? Currently using M2/OP. I'm thinking corners, since M2 is only slightly slower than comms.

I believe my execution time is near maxed out. If I could somehow get higher TPS I could improve it.

Undoubtedly corner comms.

Is corner comms strictly BH? Or is that simply the move optimal way of doing comms for corners on 3x3?

BH is really just move optimal for bigger cubes. It involves doing comms optimally, so I guess the latter part you have right.

 

[Rpotts]

and BH revolves around a fixed buffer, whereas freestyle comms do not necessarily.

N00b question for those doing TuRBo edges and similar...

When executing, how do you "remember" to undo your set-up moves properly? What goes on in your head?
I'm assuming those who can do TuRBo fast like Zane don't even need to think. But I get stuffed up.
Currently, attempting to memo the setup "moves" (e.g. R' D L2), keeping this in my head while I execute the "perm", then undo-ing (L2 D' R).

It's kinda hard, and I'm sure I'll get the hang of it. Old-Pochmann edges I could do without thinking after a few weeks, you start by doing the same set-up sequence each time, then you just "do it" without thinking about it.

(While I'm here, OMG the Turbo Algs RULE. I learnt them all in about an hour. I'm slow, but man these are good algs. Thanks to Zane and his tutorial).

Okay, so I want to start assigning my corners letters. Starting with A, should I start with the buffer as ABC? Or no? What do you guys do? Also, I solve R on F and W on U, so if you could tell me which letters you use for each sticker, that would be great!

 

[Rpotts]

I wouldn't assign ABC on the same piece. Most people just start on one arbitrary piece (often the buffer/target) and go through the alphabet around the face, then switch to another face and continue - repeat.

It is important that you make up your own letter scheme before learning anbody else's.

Or you could just use Speffz

Why? I do. It doesn't hurt.

Source-It doesn't slow me down.

ABC is on ULB
DEF UBR
etc. Clockwise. So D is on the U sticker, E is on the B sticker, F is on the R sticker. It makes more sense. That way if you have to go through the alphabet it's nice and easy to do.

I assign ABC to the same piece. What's wrong with it?

European trains must be much quieter than the London Tube if the noise
from a cube is disturbing people! The London Tube is very loud and
bumpy - no one would ever even hear me cubing on the Tube.

I was just in the US very briefly (flew back into London earlier
today) and cubed on the train there too. One guy said he'd seen
someone on TV do it blindfolded and behind their back and asked if I
could do this. I said no, but that I knew people who could. I asked
who he'd seen on TV doing this because I assumed it was probably
someone from this group. He didn't remember the name though.

Anyone done any blindfolded cubing on TV?

I have labelled the stickers corners clockwise around the cubie

So my buffer piece (Old P) ULB = ABC
Then I go clockwise around the U layer, U sticker is always the starting letter
For the bottom layer I start under the buffer piece DBL = MNO then clockwise around again (clockwise in top view of D)
D sticker is always the starting letter

Similar for edges: (Old P) UR = AB, then clockwise around. First letter is always U sticker
Then the D layer, again starting under the buffer piece: DR = IJ D sticker gets the first letter
For the EZ slice: again starting near the buffer piece: RF = Q then clockwise around until you end at RB = X

You may consider skipping Q and X because these are hard to find words for.
But as there are several word lists readily available this may no longer be an issue.

You could also skip the labeling the buffer pieces but this is tricky as you may change methods (buffer position…) later and.

What I initially liked about labeling around the cubie is that in case of doubt you can easily “count” around the cubie to detuct the right letter.

Gaetan, what's the use of "replying" to a 6 year old post on a different forum?
BTW, There is a canadian competition this weekend. You should definately go there!

nvm it just seemed really strange to me, I didn't know people used it, my bad. I'm just used to seeing a color and immediately knowing which group of letters I was working with, white is A-D, Green is E-G etc.

 

[RyanReese09]

I know I've asked this before...probably. But what's the best way to learn comms? For corners, for example, I'm using chesters site. However, even though it involves speed optimal algs, I have to rotate before the alg, which is hard as hell to find, due to me having to sort of work out what rotation I need to do. I feel like that would be prone to DNFs...

I'm thinking of doing Arons way, giving a letter pair to anki, and it spitting out an alg I have to do. Which I *could* just have it be the alg chester gives, just with the rotation that I need to do in it. Or I could find a good fast alg for each case and just use that for each case. But I'm rabbling now...I wonder if aron recommends anki...? Hoping he'll give his opinion.

I wouldn't recommend it, since over time Chester's method will give the same result as mine.

For finding rotations you need to follow a process. For example the 4 A9 cases, look at the "features" of the case. A perm has all 3 pieces interchangeable with a single turn, the other 3 have an "Adjacent non-Interchangeable" pair somewhere, and the third piece in that case has a different property in each. Instead of learning "R' U2 R' D' R U2 R' D R2" you've got to think "the third piece is interchangeable with a piece of the [AnI] pair with U, so I have to break the pair by moving 2 pieces" So instead of trying to rotate to fit a pre-determined case, just try to get all the pieces on "good faces" and work out the case, then solve it with a mirror/inverse

How should I go about learning than? Tried many ways already.

Good faces = ones easy to perform in?

4x4 BLD (U2 centers, Old Pochmann corners, r2 edges) re-cap
Ok so for 4x4 BLD,

If we have corner parity (Old Pochamnn), ULF and URB would be swapped at the end. we then restore the centers with the correct amount of U turns needed, then solve the centers. if i have parity for centers (U2 method), i'll do the parity fix(U2) at the end, then after solving, we reverse the U turns we did at the beginning, then turn the cube to the right, do the corner parity fix (t-perm+PLL parity fix), and then turn back.

there's just so many things to remember so it's really easy to make a mistake. please correct me if I'm wrong. sorry if this may be hard to understand.
