The reconstruction thread

in ETM you should count double flicks as two moves imo. if you compare L' U L' U (first U with index second U with middle) and L' U2 L' (U2 as double flick with index, middle) you see that the movements are exactly the same just in a different order. so i would count both as ETM 4.

That's how I got the name!

Brest, you're one crazy mofo!

Please take care that this reconstruction thing does not keep you from participating in the weekly comp FMC.
I'm not crazy! "It's very hard to explain why you're mad, even if you're not mad."
I have stopped doing FMC for the moment. After a series of DNFs and disappointments when practicing I was no longer enjoying it. I'm sure I'll get back into it as some time.

Seriously Brest, how long does it take you to do one of those? I'm starting to wonder if you just watch the video once then type out the reconstruction from memory.
OMG that would be the best way to reconstruct ever!
It takes me a while to reconstruct each solve, the time taken fluctuates. Sometimes the solve will be straight forward (read: CFOP with normal F2L) and those are the easiest for me. Roux solves are become relatively straight forward for me, until the mooing starts. Those crazy fast cows can be hard to track.
I often find the most time consuming part can be finding the scramble. If the inspection period is not included, or if it is obstructed, then it is hard to get the scramble. Without the scramble it is much harder for me to reconstruct the solve, especially if some of the moves are also obstructed. It is very helpful to have the scramble to compare cube states.

I tried reconstructing that one, but I think the start position looked pretty random, could just be a memorised solve sequence.
I find old videos like this, and the Waterman one, very difficult. The colours are hard for me to distinguish. I can not even tell what the colour scheme is!

Thank you Brest, you are like the best thing to happen to the forum ever <3
You're welcome, and thank you for the kind words. Perhaps a little exaggerated. =)

Ooh, thanks Brest for reconstructing my solves! You're awesome!
Dude, no worries!

Anyway I could get the last solve in this video (9.30)?
Do you just want the last one? I haven't seen a post for the other solves...

Managed to figure out Waterman's scramble (I hope):

U2 B2 D' B2 U' R2 D' L U B' D R F U2 R F R B' F'

x2 (As it sits on the table)
y x2 L2 U' D L2 D' (First layer corners)

Reconstructed from the camera's point of view and not Marc's. The rotations aren't completely execution accurate. Feel free to continue or even finish as I don't feel like continuing right now.
 
Oh, it's just like a variation of human kociemba. I think it's pretty similar to other methods which required to orient all the cube first and then permut with R2, U and D moves.
 

U2 B2 D' B2 U' R2 D' L U B' D R F U2 R F R B' F'

y R2 U' D R2 D' (First layer corners)
L B' F y' R' E2 R F' E2 F (First layer edges)
y' z2 y2 L' U' L U F U F' (CLL)
z x' U' M' U2 M' U' (One redge)
U2 R2 U2 R2 U2 (Two more redges)
x' U' R U M' U' R' U' M U2 R2 L' (Last five edges)

I wouldn't bet my life that it's correct, but whatever.

I'm interested by the number of moves for each solves.

This one could be interesting too :

Thanks :)

Thanks Brest !

First comment : lol at tps.
For the sequence description I don't know what you're calling "ODL" ? But your description seems good.
(it's me solving on the vids)

On the first solve, I just saw that there is only three corner left at a point of the solve, so I solved them instead of keep solving with the "normal method".
For the second solve, I've no idea what I'm doing after U f (R U R' U')2 f'. It seems like I didn't see I had a skip... :-o
I probably should have done this after :
L2 d L2 U y x2
U R2' F B' R2 F' B
G perm.
 
U2 B2 D' B2 U' R2 D' L U B' D R F U2 R F R B' F'

y R2 U' D R2 D' (First layer corners)
L B' F y' R' E2 R F' E2 F (First layer edges)
y' z2 y2 L' U' L U F U F' (CLL)
z x' U' M' U2 M' U' (One redge)
U2 R2 U2 R2 U2 (Two more redges)
x' U' R U M' U' R' U' M U2 R2 L' (Last five edges)

I wouldn't bet my life that it's correct, but whatever.
Oh very nice! I'm sure it's at least very close to correct. Good job. :tu

OUL/ODL --> Orientation of U/D Layer. =) I was going to write OLL, but the last layer doesn't seem to be fixed. Maybe I should have gone with O1L/O2L or just said "orientation" with no acronym.

It must be hard with these reduction type methods to be fast as well as efficient. Presumably once the pieces are separated into three layers and the U/D is oriented you just start block building, fixing parity along the way. If this is the case, then when something like L3C comes up, just solve it! It doesn't really matter if it's not specifically part of the method. If you know the case, why not solve it? I had a few goes with the method. It's fun and very different. Not that I timed the solves, that would surely be embarrassing!

When I find the time I'll most likely finish off the last 2 solves and do the 2nd video too.

Anyone? :)
I plan to make an attempt but it's missing the 1st 1.21 seconds, which is probably like ~5 moves. That will make it much more difficult. I've been looking forward to this video since the competition so I'm really disappointed the start is missing. Shame on Fazdad, shame on you! =)

If applied correct the scramble should be one of these 2:
Finals 1 1st solve:
B' Fw' Uw' Lw2 R2 F Rw2 B' Bw2 F L' B Fw Dw' Uw2 U' B' Bw2 Fw Uw' B U' Bw' Fw2 Dw' U2 Fw Dw' Fw2 L F' R2 F2 U2 L' Bw Fw' R' U2 Lw' Dw' R2 Uw2 U2 B2 Fw' F Lw2 B2 Lw' Uw2 Bw Dw' F Dw2 U2 Lw' Bw2 Dw' U

Finals 2 1st solve:
Lw' Dw2 B' Lw B Fw2 R2 Bw Fw2 U' L B' F' R2 Fw D' Fw2 F2 Dw L2 R' D2 Lw R2 Uw' Lw Dw Lw2 Dw Uw' U B' Fw' L R' Dw Lw' Rw' Bw2 Dw' L2 U2 Bw' Lw R' Dw' Uw Bw' Fw D2 U' F D2 Fw' U' Rw2 U2 Lw' Bw2 L'

Anyway, I'm going on holiday so I wont be doing many, if any, reconstructions for a while.

Yeah I'm not sure about the end. Finding the scramble was pretty tricky but fun, had to look at it when it sits on the table, when he has three corners done and when he has four corners done to find out the location of all pieces.

Yes, that's it. And, I think you can call the orientation step just "orientation" 'cause there is not really other explanations.
