On Joey's scramble: 1:05 DNF

@tim
Umm, so lucky solves happen all the time for you? Think about this. Do lucky solves happen on speedsolving as often as you have one piece solved on a scramble? Of course not. Therefore, a lucky blindsolve should be something that doesn't happen that often. I consider a lucky blindsolve to be one where 20% or more of the cube is done. So on a 3x3 >4 pieces solved, which doesn't happen very often.

20% is a somewhat silly thing to say.
I'm tooo lazy to find the chances for >4 from http://cube.garron.us/BLD/probabilities.htm, though.

But please also don't forget how tim memos.

Remind me how does Tim memo? And why is 20% a silly thing to say?

The first successful solve on my first 7x7x7 cube was a BLD solve! Yes!

how'd you solve it after DNFs? BLD again?

I only had one DNF, so I only had to deal with it once. What I did was, I solved it to all but 3 wings that needed cycling, then I applied the first few moves of the second scramble, then I solved the 3 wings with a commutator, then I applied the rest of the scramble. It worked great!

I use a fixed buffer, so i waste one image per extra cycle. I once kept track of 55 bld solves. 18 of them had less than 19 pieces to memorize + execute. That's 33%. If i change the criteria to <18 there are only 6 attempts left. So i think calling scrambles with <19 pieces lucky makes sense for my system.

btw. Remember, that a permutated piece affects memorization + execution time.

After four months of DNF for 3x3 BLD, I finally got one!!! Time was 5:02. Oh, Jesus, I'm so excited lol.

 

[cmhardw]

Okay, I could not possibly be more excited:

7x7x7 BLD: 1:57:04.84 (57:45 memorization)!!!!!!!!!!!!

Congratulations Mike! That is simply awe inspiring! I have yet to try a full attempt. I just got back from my trip today, and I did scramble up my 7x7x7 and start memorizing the inner t-centers but I'm simply too jet lagged right now to concentrate. Will try a full solve sometime this week once I rest up.

Congrats again, this still looks like an intimidating feat to me (I haven't yet tried to memo the whole cube). Even my longest journey (32 locations) is too short for me to memorize everything using images. So I need 2 journeys to memo this cube! Insane!

--edit--
I just did a 5x5x5 BLD solve on my V-cube and got 15:56.48 which is pretty good for me. On my rubiks.com cube I have to turn pretty fast the whole time to get a solve like this, this V-cube is much smoother than my rubiks.com cube! The black was a bit weird at first, but I don't forsee it really bothering me. I plan to use my V-cube 5x5 for Nationals (so far).

Does this mean you turned "pretty fast the whole time" for your world record?

 

[cmhardw]

Does this mean you turned "pretty fast the whole time" for your world record?

Very much so, I was upset that I had DNF'd both 4x4's and the previous 5x5 before that solve. Partly in frustration and partly in desperation I went very fast on the solving phase (not memo) for that solve. Jason, my judge, told me after that I finished memo at around 9:30, putting my solve time at about 5:55 ish (sub-6 min), which as far as I know is my current personal best solving phase ever, even at home.

Do any of you guys ever do 2x2x2 BLD? I was thinking about cubing the other night and realised that i had never tried a 2x2x2 BLD. I took my 3x3x3 BLD knowledge and did a 2x2x2 in 2:35, first try

Tonight i've done about 50 2x2x2 BLD solves and my PB is now 1:28. Man this is fun

 

[joey]

Hehe 2x2 BLD is fun.

Nothing wrong with using multiple journeys. It makes it more like Roman Rooms, where things are automatically partitioned into related things. It sounds like you have more than one journey - just use multiple - it should work out great.

Good luck - I'm confident you'll get one soon. Now if I could just get a 6x6x6 BLD (2 failures so far - both off by just 2 obliques).

I wish I had time to do more 7x7x7 BLDs, but I want to get a 6x6x6 BLD, and then I'm also having to practice for multiBLD for Nationals. (Since there's no 7x7x7 BLD event, I can't really justify practicing it hard. But I'm going to focus on it and 6x6x6 BLD as soon as Nationals is over. I'll probably do all 3 scrambles of both each week if I can, at the expense of multiBLD. I love doing real big cubes BLD!)

I just did a 5x5x5 BLD solve on my V-cube and got 15:56.48 which is pretty good for me.

--edit--

I tried using my 5x5x5 V-cube for the scrambles this week and DNFed them all. On the second one, one of the wings twisted and almost popped out. I'm really not sure I like my 5x5x5 V-cube for speedsolving, even, but I'm sure I don't like it as much as Eastsheen for BLD. I've decided to stick with Eastsheen for Nationals. (I'll have the V-cube there as a backup.)

Just did a 51.75 2x2x2 BLD

I already thought you would like > 1 BIG cube blind scramble Mike. That is the main reason I made it 3 scrambles, but that's also the main reason I added the note that you don't have to do them all

I also think the V-Cube 5x5x5 is no where near as good (yet) as the Rubiks 5x5x5 I own, but at least the V5 doesn't pop.

And V-Cubes really shouldn't have those black stickers. I hope CubeSmith will sell replacement stickers/tiles for them (5x5x5 -> 7x7x7) during the US Open. I would start with replacing just the blacks with white. My mind keeps refusing/confusing the blacks and even converts them to other colors during edge-pairing. I see a green/dark edge and start looking for green/blue (which doesn't exist )

 

[Simboubou]

My first official multiblind attempt was successful !
5/5 in 43 minutes, National Record !

I already replaced my stickers with the usual color scheme; prior to doing that it was even worse. (I had bought a bunch of Cubesmith 5x5x5 stickers before getting my V-cubes, so I could resticker as soon as I got it.)

You say the V5 doesn't pop; it was the near-pop that I got during a 5x5x5 BLD solve that scared me from the V5. I'm just not sure I can ever use a V5 for BLD again after that - it scared me badly, and I'm pretty sure it was the commutator I was working on at the time that I messed up that gave me the DNF. That's what I like about Eastsheens; until they've popped for the first time, they can go months without ever popping - not even once. (Unfortunately, after they pop the first time, they're not as good anymore.) And I can't say that for the V-cubes.

Oh, and thank you Arnaud for being so considerate towards me in providing the BIG cube BLD scrambles. I figured all of that was for my benefit - that was very kind of you.

 

[bubblebuddy73]

My BLD goal is to get sub 3 minutes and than hopefully average that... Right now I average about 3:50.xx using M2 / Y perm. Also i would like to get a 2/2 multi BLD. My first attempt resulted in 1/2 in 16.xx.xx minutes, and the cube that I DNFed was only 3 edges off. Oh well...iil keep trying!

 

[AvGalen]

Providing 3 scrambles was for both you and Chris. Telling you that 1 is good enough was meant just for you

 

[joey]

46.88 BLD

Personally I don't think it is lucky, for my method.

L2 D L' D2 U B' F U L' B' L F' L' U' L B2 L D2 B2 F' L2 R F' L U2

1 edge in place. 1 corner in place.

Let's hope I can do this next weekend at Czech Open.

 

[Mike Hughey]

Wow, Joey - that's amazing! Good luck in competition! I want to see a sub-1!!!

 

[joey]

Heh, me too. Sub-50 would be pretty damn awesome too! (That was my third I think, 48.11 44.21 46.88)

 

[fanwuq]

Some nice 2x2 solves. I suck at memorizing edges for 3x3 still.
