Melbourne Cube Day 2010

Well come on then, me want more videos. I've only seen both 3x3x3 WRs and the 4x4x4 WR.
 
FMC scramble?

U B2 L2 B2 D L2 B2 R2 U2 R2 B U2 F2 L2 U L R2 D R2 F U'

Am stupid. I saw bottom 2x2x2, and went for it, as it was right in my face. Now that I look at it, there were better options. I just couldn't believe my luck, that I'd gotten what I thought was a nice scramble. I found 23 moves to 4 corners in about 10 minutes. Spent 30+ minutes trying to finish it. Then realised this wasn't all that good in terms of starts. I then found 28 moves to 3 corners (27 + aligning), but didn't realised I still had over 20 minutes left, so I went with this. Searched and searched, but I couldn't find an insertion that cancelled, so my solution was 36 moves :(
B' D2 R B R' D R U' R' D2 F U2 F' B2 U F' U' B2 U F U' L U L2 F L F' L' R' F' R F' U F U' F (36)
Can someone improve on this insertion? It's in bold.

There are 4 canceling insertions based on your skeleton, that I can find at least. Three of them are 8 move commutators that cancel 1 move. One is an 11 move commutator that cancels 4 moves.

B' D2 R B R' D R U' R' D2 F U2 F' L U L2 F L . F' L' ! R' F' R F' U F @ U' # F

. = [R2 F L' F' R2 F L F']
! = [L F R2 F L' F' R2 F L F2 L']
@ = [B D2 B' U B D2 B' U']
# = [U' R' D' R U R' D R]

Only perform one of these insertions, not more. Each one performed individually is a 7 turn insertion with one or more canceling moves.

Finally some spare time;
DYK...
- Arnaud is really cool?
- I arrived at 8:40~ but realised all I knew was it was at RMIT, and not sure of anything else. So I cubed out the front of the main building with a view up both main streets. I cubed until around 9:10, at which stage I realised I must be in the wrong spot completely. So I ran up Anthony, but he was lost too. We met up, then finally found it... 16 buildings away from where I had been?
- The venue was amazing?
- I posed with Faz's cube after the 6.77, with a mock victory style. HATERS GONNA HATE.
- I called it? I posted in that thread, predicting today (I only thought once though...)
- His 31.9 4x4 WR, had literally no claps, bar me. A lot of others had left, and this was on a far table?
- Even when we announced that his 4x4 average was 35.80, it remained fairly quiet?
- This was my worst comp, results wise, but still, an awesome comp?
- Me and Luke were very annoyed that we made 2x2 final?
- So annoyed that we started off with 3, 3 and 4, 3 respectively?
- Arnaud was present for my 7.08 2x2 solve?
- David Edwards pen flipping world record average. Faz single?
- In FMC, I spent more time on my backup solution, than my solution? D:
- J-line bragged to me, about his 1:15 4x4 solve, saying "beat that". I replied pointing to the display that I'd just solved at, saying, "just did, 1:11, pops and parities?
- Lol Yau?
- "Only 7" (someone in response to another's, "how many world records today?")?
- 7.03 was joined with a mega roar, and many finallys! Too bad I was judging 8 stations away, and too short to see over the crowd that had gathered?
- My 2 13s in the final had Zperms starting at 9~ and 10~?
- I started an Eperm in an OH solve at around 15? :(
- The D in Arnaud is silent, according to Fazdad?
- I had 3 pops, OLL parity on every solve, and 3~ PLL parities in my better round of 4x4?
- I could've had numerous sub ones, if it wasn't for all these parities and pops?
- Luke had a counting 57?
- I popped on the 3rd last move of a Uperm, in 4x4?
- Luckily Brian chose to randomly film that solve, so others could share my pain?
- To be honest, I was absolutely shocked with Faz's 7.91 3x3 average like everyone else, because I've seen him do better at meetups?
- His 4x4 average and single however...

Edit: Chris... I can't believe it... I had insertions in those spots, but they didn't cancel. :( I have limited knowledge of insertions I suppose. Thanks for this.

I think everyone noticed this one, as on video it appears you grab the cube before the judge has finished the closing procedure of the solve :eek:

BH corner algorithms are extremely useful for insertions. Also, sometimes at a point where the insertion looks nice there are often multiple algs you could perform that execute the same 3 cycle. Make sure to try all possibilities if an insertion looks good.

I disagree. If a 9 move alg canceled more turns than any 8 move option, then I would use the 9 move alg. If it gives a fewer net added moves for the insertion, then I will always use that alg, even if the alg itself is not 8 turns in length.

Could you give an example of a 9-move insertion that would result in a shorter solution than if you inserted a 8-mover instead?

My ~15 minutes try:

B' L2 F' L2 D [2x2x2 (5)]
U' L F L2 U2 [2x2x3 (10)]
F2 U' F U F' L2 [F2L-1 (16)]
F2 L' U L U' [F2L+EO (21)]
U F L F2 L' F' U' R' F R F' [LL (30)]
 
- Arnaud is really cool?
Avg: I figured out why Faz is so fast. He saves the speed for cubing, so he's really slow in real life.
Faz: Wait, what?
Avg: He'll get it in a minute.

I know it didn't go exactly like that, but still funny.

I got a bit lost too, and wouldn't have got there if there weren't lots of people telling me where to go. My Mum wanted to know which way a street (can't remember which one) was, so she asked the first person she saw. It was Dene. :p
- The venue was amazing?
I agree. Very quiet and calming (I think it was the meditation room), and the lighting was good.
- This was my worst comp, results wise, but still, an awesome comp?

Same with me. Well, my results were bad in the events I cared about.
- David Edwards pen flipping world record average. Faz single?

I think I saw him get a 0.55. :eek:

- J-line bragged to me, about his 1:15 4x4 solve, saying "beat that". I replied pointing to the display that I'd just solved at, saying, "just did, 1:11, pops and parities?

I got a 1:11 too, but it was a no parity PB. :p

- Luckily Brian chose to randomly film that solve, so others could share my pain?
I chose to randomly film one of Faz's 4x4 solves... 31.90.

DYK...

-I suck at FMC? 51 move solution that apparently didn't work, even though I checked it.
-I rarely practice 4x4 and OH, but got into the finals, yet I didn't get into the 3x3 finals, when I practice it a lot?
-EVERYONE HAS GOT SO FAST AT 3X3? (Luke and Nick.)

A few posts back, Chris showed some 8 movers to cancel 1 move, and an 11 mover to cancel 4 moves, so that is equal. I'm quite surprised you actually asked this. Surely you realise that more often than not, 8movers are more efficient than 9 or 10 movers, doesn't mean they always are.
