Weekly competition 2009-04

[mpohl100]

I've been starting fewest moves two weeks ago and now this is my first try for the weekly competition.

Scramble: L F2 L' U2 L2 U2 F2 R2 B2 F2 D R' B2 L' B D' L2 F' R' D' F2

Here is my solution:

2x2x2: R' B2 R2 B' (4) (pretty obvious I think)
1st 2x2x1: R F' R2 U' F2 (5) (The U' is a setup move for the 2x1 block)
2nd 2x2x1: U R2 U' (3)
Finish F2L: B' R' B R' F' U R (7) (B' R' B to setup the 4th pair)
Edge Orient: R U B U' B' R' (6)
COLL: R U' L' U R' U L U L' U L (11)
PLL skip (lucky but chance was 1/12)
AUF: U'

That makes a total solution of:
R' B2 R2 B' R F' R2 U' F2 U R2 U' B' R' B R' F' U (R R) U B U' B' (R' R) U' L' U R' U L U L' U L U'

=> 34 moves with a PLL skip which means that it is quite lucky
BUT I am very proud of my 19 move F2L

I still need mor practice.

3x3: 13.40, 15.12, (15.43), 13.80, (12.93) = 14.11
Three good solves, resulting in a good average.

2x2: 5.05, 5.52, (6.41), (4.76), 5.19 = 5.25
Distinctly average

4x4: 1:15.81 P, 1:20.51 O, 1:21.01 OP, (1:06.72), (1:21.26 O) = 1:19.11
Awesome single solve in there, but a normal average.

Sq-1: 45.19 P, (42.72), (1:00.37 P), 50.82 P, 46.07 P = 47.36
That's a lot of parity, there. I messed up the third one, but the rest were OK.

3x3 BLD- DNF, DNF, DNF
Comment: Second scramble was a joke. Still flipped two edges. I need do to more than these three BLD solves a week.
Square 1- (2:28.31), 3:57.44, 3:01.11, 3:43.27, (4:12.53) Average- 3:33.94

I've been starting fewest moves two weeks ago and now this is my first try for the weekly competition.

Scramble: L F2 L' U2 L2 U2 F2 R2 B2 F2 D R' B2 L' B D' L2 F' R' D' F2

Here is my solution:

2x2x2: R' B2 R2 B' (4) (pretty obvious I think)
1st 2x2x1: R F' R2 U' F2 (5) (The U' is a setup move for the 2x1 block)
2nd 2x2x1: U R2 U' (3)
Finish F2L: B' R' B R' F' U R (7) (B' R' B to setup the 4th pair)
Edge Orient: R U B U' B' R' (6)
COLL: R U L' U R' U L U L' U L (11)
PLL skip (lucky but chance was 1/12)
AUF: U'

That makes a total solution of:
R' B2 R2 B' R F' R2 U' F2 U R2 U' B' R' B R' F' U (R R) U B U' B' (R' R) U L' U R' U L U L' U L U'

=> 34 moves with a PLL skip which means that it is quite lucky
BUT I am very proud of my 19 move F2L

I still need mor practice.

That COLL doesn't work. Can you check what it should be?

edit: ah, found it. The first U should be U'

You know, you could also correct it in the total solution

3x3x3 :31.43, 36.11, 32.68, (37.86), (23.08) = 33.41
that last one was insane.

4x4x4 :(2:59.31) , 3:17.84, 3:02.31, 3:46.78, (3:49.27) = 3:22.31
horrible, OLL parity on every one, bad cube too.

3x3x3BLD :DNF (6:39.94), DNF (6:09.74), DNF (5:22.47) = DNF
using a new memo system...

snake :(5.97), 5.47, (5.15), 5.81, 5.44 = 5.57
PB single and average.

 

[Jacco]

2x2: 4.81, 5.83, (7.31), (4.72), 6.64 = 5.76

3x3:17.44, 16.69, 16.92, (16.39), (17.97) = 17.02
Ok.

4x4: (1:16.97 (OP)), 1:21.09 (O), 1:18.20 (OP), 1:25.50 (OP), (1:40.30 (OP)) = 1:21.60
Terrible, stupid parities :rolleyes:.

5x5: 2:13.80, 2:03.14, (2:19.69), 2:05.58, (1:55.02) = 2:07.51
Average

3x3 OH: (27.92), 28.09, (44.74), 31.53, 28.38 = 29.33
Average. The 44.74 was so totally screwed up , wrong cross, wrong f2l case, mistaken on OLL..

3x3bld: 2:02.80, DNF (2:28.83), DNF (2:30.58) = 2:02.80
Bad


3x3 Fewest Moves: 35 moves, very good for me =) (I never practise).

(scramble: L F2 L' U2 L2 U2 F2 R2 B2 F2 D R' B2 L' B D' L2 F' R' D' F2 (21f))

2x2x2: (1:21:01), 1:14.46, 45.92, (39.23). 1:12.40 -- (very-beginners' method!)
3x3x3: 1:06.55, (51.64), 55.45, 1:05.88, (1:08.53) -- (New cube, just stickered, not yet lubed, thumb injury!)
4x4x4: 7:11.42 (rather drunk due to Burns' Night celebrations, had to stop half way to fix the television for my wife!) DNF (completely messed up trying to fix parity!) (yet to be completed)
5x5x5: 10:18.00, 13:39.00 (rubbish at tredges, stupid mess up trying to do 4LLL),(yet to be completed)
7x7x7: 27:49.00, (yet to be completed)
MegaMinx: (11:36.00), 8:26.45, 8:49.99, (6:33.84), 7:32.76 -- (new PB lucky OLL skip)

FMC:
DNF, just couldn't find any good continuation for any of plenty of short 2x2x3 blocks. Only after almost 2 hours here was a lucky PLL skip.

[bubblebuddy73]

2x2
3.90, 4.69, 4.59, 6.16, 5.86 = 5.05
Not bad. I used to avg in the high 3's but I now learned CLL and am still practicing it.

3x3
12.68, 14.02, 19.13, 13.91, 14.02 = 13.98
WOW. I was really working on lookahead and i think that is my best avg.

3x3 OH
21.59, 22.91, 24.30, 22.59, 20.80 = 22.36
Good.

2x2x2: 6.31, (19.20), 8.08, 4.58, (4.06) = 6.32 --> Still relearning my bad CLL cases, so that's why the first 3 were terrible.

3x3x3: 21.17, (22.11), 19.94, (18.75), 22.08 = 21.06 --> Average for me now, considering I only do 5 3x3x3 solves a week!

3x3x3 OH: 31.48, 31.66, 31.20, (25.59), (DNF) = 31.45 --> Again, I'm ridiculously out of pratice. The 4th solve is what I would've once called "average" for me It was non lucky, for some reason I could just turn with one hand like I used to!

3x3x3 BLD: DNF, DNF, DNF = DNF --> Uhh, 2nd week in a row I've got 3 DNFs

Comment: At least I got a solution in time this week (perhaps the last week for this). It would have been nice to work on each of the solve phases a little more. Argh! I could have reduced the solve by 10 moves simply by using a Fridrich-style ending to the 3x3x3 phase. After 2nd slot: (R U2 R') (B U2 B') (F' U' L' U L F) (B2 R' U' R B2 L' D L' D' L2) (95 moves for whole solution).

5x5: 2:09.46 (2:00.22) (2:24.16) 2:11.95 2:11.08 => Avg: 2:10.83
I have so much room for improvement. I expect sub-2 during practice next weekend.

6x6x6bld DNF
1:43:22.73 and about 58 min for memorization. I thought I had to do it for 2 to 3 hours. Corners are solved, 7 inner wings, 6 outer and a lot of center pieces wrong.

Wow - very nice to see someone else try! And I think it's awesome that someone's doing more events than me now!

5x5BLD: 42:32 (24:24) = 42:32
(HOW ABOUT THIS ONE!!!!!, PB)

Good to have you participating, and nice solve!

 

[oyyq99999]

3x3BLD: 4:17, DNF, DNF = 4:17
(second one was so easy I got confused and dnf:ed)

4x4BLD: 17:03 = 17:03
(new PB, I'll save the others for sat/sun)

5x5BLD: 42:32 (24:24) = 42:32
(HOW ABOUT THIS ONE!!!!!, PB)

I've loaded the 5bld for tomorrow morning, and how well that went!!!

Mike:
As to 6x6 bld I will try when I get one, but I do not own a 6x6 cube yet.

I am confused that is it I do 3x3x3bld too fast or big cubes too slow. I am much faster than you on 3x3bld but almost the same time with you on 4x4bld and 5x5bld.
I tried a 6x6bld today and it took me 1hour and 4x minutes. Hoping for your solve!

Comment: Horrible...

3x3BLD: (DNF 1:35.29), 1:25.16, (DNF 2:08.60) = 1:25.16
Comment: I should really start practicing again... just horrible

MultiBLD:

It's a BLD kind of week!

 

[guusrs]

FMC:
I agree with Mirek. Many short 2x2x3 blocks possible, starting from 7 moves, but bad finishes left all the time. Finally this one gave me an acceptable edge-skeleton:

2x2x2: R' B2 R2 B' (4)
2x2x3: R' F D' F' D (9)
F2L minus pair: F R2 F2 R' U2 R F (16)
edges: U'.R2 U R' U F' U' F R2 (25)

Normally I do not start a corner insert on a 25-move skeleton but with 10 minutes left this was the only option I had to get a solution close to 30 moves.Good cancellation helped to get sub-30: At dot insert . U' L' U R2 U' L U R2 , 4 moves cancel. So finally:

R' B2 R2 B'R'F D'F'D F R2 F2 R'U2 R F U2 L' U R2 U' L U2 R' U F' U' F R2 (29)

FMC: 31 moves R' B2 R2 B' R F' R2 F2 B' R' F' R B R' F' U2 F U2 R' U2 R' U2 R U R' U' R U' R2 U R

just noticed its entirely 4-gen. neat!

2x2x2: R' B2 R2 B' (4)

2x2x3: R F' R2 F (8)

EO: F R'. F2 U2 F (13-1)

leave 3 corners: U2 R' U2 R' U2 R U R' U' R U' R2 U R (27-1)

insert R B' R' F' R B R' F at the . to cancel 3 moves. F F cancels to F2. after some bad continuation of a good block, I decided to try EO and stumbled upon this finish. Good insertion helped. This one is tough!
