qqTimer can be more accurate than a stackmat.
because you can't get a 0.00 with a stackmat!

sometimes I just keep hitting the space button so fast that the timer doesn't even stop.

You can get 0.00 on a QJ timer.

Athefre/Cride - I still think your 2x2x2 methods are too complicated - too much to remember!

However,

I think what sets apart an intuitive method from an algorithmic method is that the details don't really matter ... as long as the solver is aware of the sub-goals to be reached, they should be able to kludge together the bits in between, even if the exact moves have been forgotten.

I've actually seen this happen at the "solve all edges" point in 8355. The guy I taught made up his own system for doing it.

How about the '35' method :D


@ariasamie, just because a timer can register better time resolution doesn't mean it's more accurate. A general problem with PC based timers (and this includes CCT) is that they share processing with other tasks. If your computer decides that some task is more important than 'stop timer' then your times are going to be wrong. Personally, I would trust a Stackmat/QJ timer more than anything on a PC.

idk man, it's better - but it's still confusing. I was hoping for something really intuitive - something I can teach someone in 30 seconds.

The biggest problem is solving the adj swap intuitively. Doing one move and solving the corners again gets confusing because people forget where the corners are supposed to be.

The problem with adj swap is that any alg for it is going to be at least 9 moves. It's very difficult to break that down into intuitive sub-steps.

The method I suggested makes half of the moves (the final 5) completely intuitive and difficult to mess up, because the cube is reduced to the R2, U group. As long as they don't let go of bottom-left two cubies, it should be a doddle.

The hardest part is the first 5 moves, setting up for the re-grip. It requires the solver to remember:
* Bring DR pair up to UB
* Break it up
* Do the R2 swap
* Regrip

... I can't really think of a nicer way to do it. Perhaps some kind memory trick would help. ... like an acronym for the steps. All I could think of is: BASS (Back, And Split then Swap).

Easy to remember two-swap on back (for 2x2x2):
R2 D2 (R'F')*7.5 D2 F2

I had the idea of making a StackMat-like timer that runs on 1000 Hz (yes, three decimal places) instead of 60 Hz. I don't know if this is a reasonable modification but I'm going to give it a shot.

I... suppose that could work? It would also make things easier if you happen to already have an extra magic lying around, because I certainly don't.

I know. I was just joking :)

Another LL method me and Rob played with; FreePLL/PureOLL

FreePLL;

Y- F R U R' U' F'
V- R U' R' F R F' U R
R- R U R' U' R' F R F'
A- Niklas
U- Sune
N- R U R' F' L' U' L F
J- R' F R U R' U' F U R
G- R U2' R' U2 R' F R F'
T- R U R' U R U' R' U' R' F R F' / F R U R' U' R U' R' U' R U R' F'
E- R' U' R U' R' U y' R' U R B / R U R' U R' F R F' R U2 R'
F- F R U' R' U R B U B' R' F'
Z- F R U R' U' F' f R U R' U' f' / R' F' U' F U R2 B U B' U' R'

We never generated all the PureOLL algs, because they suck. So here's 2look; (The EO algs affect some corners, too. The adj alg might actually be useful for other things)

EO;

Adj- R' U' R2 B' R' B2 U' B'
Opp- B' R' U2 B U B2 R B R2 U R2 B
All- R' U' F' U F R F R U R' U' F'

CO;

L- [r' u R2 u' r, U2]
U- (RBS) (RFS)
T- (RFS) (LFS)
Pi- R U2 F2 R' U' F R' U2 F' U2 R2 F U R' F U2
Sune- U' B U' F U2 B2 D' R2 U D F' U' B
H- U R L' D' R2 U2 R' D R2 U2 L U' L2 B2 L2
