Weekly competition 2007-21 (2,3,3OH,4,5,BF,SQ1,MG), 2007-07-02

The competition really seems to inspire people. Lets see how many new competitors we get this week. Pleae notice the addition of Magic! I don't know how many points to give it, but please let me know what you think! My idea would be to give it the minimal amounts of points (1 for participating, 3/2/1 for places 3/2/1).

Magic
1. Dubble fold, star Shape, rotate left 2......Just kidding, just do 5 solves!

Results from the last 3 weeks will be available in a couple of days in this topic:
http://z12.invisionfree.com/rubiks/index.php?showtopic=614
As always: Competition starts now and ends sunday/monday nightchange (officialy), but I will only close a competition after the new one is on-line.

This weeks competition includes Square-1 and Magic because they finally got 10 votes. It still doesn't include most Other events for competition yet because they haven't gotten 10 or more votes yet. If you want more events, please vote in that topic! Some puzzles ALMOST have the 10 votes, so you can make the difference!

Name: Erik Akkersdijk

Magic: 1.12
Times: 1.17, (1.08), 1.11, 1.09, (2.94)
last solve was a screw up, these are the first 5 solves since german open I think...

sq-1: 1:06.88
Times: 1:07.40, (59.26), 1:01.54, (1:14.01), 1:11.71
Quite good times with rubbish method sub-1 avg soon

2x2: 4.15 avg
Times: 3.92, 4.3, 4.22, (3.78), (4.67)
no warm-up, ok solves

3x3: 13.10
Times: (13.77), 12.95, 13.53, 12.83, (12.72)
bad... ( )

OH: 28.67
Times: (24.58), 28.97, (33.45), 27.83, 29.22

4x4: 58.99
Times: (1:11.36) OP, 58.55, (56.92), 59.13 (P), 59.28 (O)
Reasonable times

5x5: 2:04.68
Times: (1:49.38), 2:07.70, (2:18.95), 1:59.14, 2:07.14
Seems like I used all my 5x5 skillz for today in the first solve


---BLD---

2x2a: DNF (38.00)
2x2b: 36.39 good

3x3: 3:23.44, rubbish memo...
3x3: 2:19.64, edges took like one minute to memorize so the rest was quite ok

3x3x3
Average: 48.79
(44.22), 46.09, (57.86), 54.14, 46.14
big drop from last avg, probably because i was practicing f2l today for quite a while, so, warmed up for fridrich

3x3x3BLD
DNF (was a 4:45, looked like i built 2x2x2 and thats all ^^. going too fast for my own good >_<)
DNF (was a 5:20, messed up 1 edge permutation cycle, damn)
^
that's what i get for trying to bld before doing at least one bld solve. i'm hopeless if not warmed up

Erik: can you describe your "rubbish" method for Square-1? I think mine is even worse! How do you avoid/solve parity?

hait2: I feel bad about my blindfolded skills now. I can never do a warm-up, because that would take up memorie-space that would influence my next solve. Also, I am always glad if I finish under 10 minutes.

Does anyone know of a +30 year old cuber that can actually solve a 3x3x3_bf in under 5 minutes?

Well, there's me! I haven't beaten 5 minutes in competition yet, but hopefully I will this time. I just got my best time of 3 minutes, 34 seconds on a non-lucky blind solve 2 days ago - I was pretty excited. My average is just a little over 5 minutes now, and going down fast.

I'm 45(!!) years old, and I have only been blindfold solving for 3 1/2 months. It seems to be my strongest cubing event.

I've started to wonder - were there any older competitors than me at the US Open?

Magic: 2.43
3.17 2.06 (1.81) (DNF) 2.06

Wow, first sub-2!

2x2x2: 16.02
12.28 (DNF) 15.94 19.84 (11.88)

Should take this one seriously... Still haven't learned Ortega.

3x3x3: 30.63
31.09 30.55 27.47 34.91 30.25

Lookahead died, X-crosses gone wrong...

4x4x4: DNF
DNF 1:22.41 1:40.56 DNF DNS

First time I screwed up the centers and messed up fixing them, 2nd DNF was when I screwed up the O parity fix. Otherwise, two nice solves (new PB too)

5x5x5: 2:34.61 / 154.61
2:55.03 (DNF) 2:20.05 (2:18.61) 2:28.75

Told you I was in a cube slump... 2:55... Sigh.


Way too many DNFs, but 2 new PBs, so I guess it's okay...

2x2 BLD: DNF
DNF DNF

Going back and looking at my solutions to both solves showed errors in memo...

3x3 OH: 2:08.20 / 129.20
1:59.03 (DNF) 2:27.48 (1:25.19) 1:58.12

4th solve was very easy... But forgot F perm and R perm for the rest of the solves (almost forgot T perm, but barely got that one).

Rubbish method of mine has improved slightly.
It was:
gather edge -> make cube shape
make one correct layer of permuted corners
permute the other layer corners with pochmann prinicple (now with one formula from Lars' site)
orient 6 of the edges with one formula
shoot with the same formula to the D-layer so that the D-layer is permutated correctly.
Permute last edges with pochmann principle and fix parity

So all in all formula's I know:
1. the formula to make the cube shape after edges.
2. the pochmann prinicple for permutating corners/edges
3. alg for switching UR and DR edges (also switches UB and UF)
4. parity

Thanks for explaining, but it is still a bit vague. Do you have a url/site where this is explained? More importantly: Could you please tell me how to fix parity WITHOUT having to restart?

Hey Arnaud

For the parity on one layer we both use the algo
/ (3,3) / (-1,0) / (2,-4) / (4,-2) / (0,-2) / (-4,2) / (1,-5) / (3,0) / (3,3) / (3,0)

It swaps 2 edges ---> same principle as on 4x4.
Learning it sucked a bit

Wow, that is a long and difficult alg! But it is definately worth learning it.

I just learned this simple one (/3,3/-1,-2/-2,2/2,-2/1,2/-3,3/) which is just 3 moves to remember, because the other 3 are just the inverse. The problem is that everything is messed up again after this alg. The alg is useful for a beginner (like me, because I can now solve the S1) and for a very advanced solver that can see if he has parity directly after making the square-shape (is that even possible?).

Maybe it would be good to open a Square-1 topic to discuss this puzzle further.

2x2x2
Average: 14.55
Times: (22.81), (12.84), 13.55, 16.91, 13.18

Still waiting for a new 2x2...

3x3x3
Average: 24.82
Times: 25.02, (23.71), 25.43, 24.02, (28.41)

Horrible times! I just did a good average of 10 before this, so I don't know why they are so bad!

3x3x3 OH
Average: 48.33
Times: 58.18. (37.31), (60.78), 41.77, 45.05

This was a really good average. The second was my PB. The times were kind of wierd, the solves were like bad, good, bad, good, good.

4x4x4
Average: 1:50.68
Times: (2:07.03 OP), 2:02.96 O, (1:36.77), 1:50.41, 1:38.66

Lots of bad times, even though I was lucky with the parities...

5x5x5
Average: 4:43.30
Times: (4:13.97), 4:48.06, 4:45.05, (4:52.22), 4:36.78

Square-1
Average: 1:51.41
Times: (2:16.68), 2:04.53, 1:33.93, 1:55.78, (1:22.50)

Parities almost every time. I am so slow at this...

Magic
Average: 2.01
Times: (1.84), 2.27, (2.34), 1.86, 1.90

Wow, really consistent! Normally, I go as fast as a can and get lots of DNFs, but I tried slowing down, and got a really good average!

BLD
2x2x2: DNF
2x2x2: DNF

3x3x3: DNF
3x3x3: DNF

I never get successful solves in the competition! The first one was really screwed up, the second I forget several edge cycles (which I always do)

4x4x4: DNF
4x4x4: DNF

These were my first two attempts ever. The first one I messed up corners and stopped in the middle, the second I think I messed up on the centers. This is so frustrating!

Andy Tsao
3x3x3: 14.47 (14.73) 13.67 (13.28) 13.80 = 13.98
I guess this is acceptable for the first 5 solves of the day....
3x3x3 BLD: 1:38.94 1:42.08
Bleh...
3x3x3 OH: 27.61 31.45 28.70 (31.92) (25.28) = 29.25
Ok I guess...

masterofthebass has an interesting way of solving parity... I can't verify it myself, as I am out of town and don't have a Square-1 with me, but he does something like -1,-1 and then a z2 and then just swaps the two edges with the regular swap-two-edges algorithm...

When scrambling the 4x4 and 5x5, are the letters like r double layer turns, or slice turns?
