zomgj iz dat uwrrrr?!?!?

[MM99]

Can Brest do a breakdown please?

 

[scottishcuber]

What are you averaging now?

 

[rowehessler]

What are you averaging now?

it varies. stack mat usually 2flat, i just got a 1.86 avg12 on video with spacebar. I gotta stop being lazy and going back to spacebar haha.

Sub- WR!

 

[Dapianokid]

ur rubrik kyoobing iz beeyund ush allllllllllllllllllll

Seriously, though. 2 move scramble? lawlawlawl

No, 9 move scramble :/

2 move solution :/

 

[Dapianokid]

No, 9 move scramble :/

2 move solution :/

I just don't even.
Stefan, what are the chances of that and tell me how you got that numbr so I can know later without having to ask? :3

 

[Michael Womack]

I want to know if Brest could reconstruct the solve.

If the scramble is uniformly picked up from any state (including the solved one), then a 2 move scramble has a chance of 54/3674160, which is equivalent to 1/68040.

Here is the source.

54 states has a 2 move solution, and there are 3674160 states.

I want to know if Brest could reconstruct the solve.

I know I'm not Brest, but:

Ok thanks and that will work.

I know I'm not Stefan, but:

24 possible one movers, 24 more from there, 24*24 = 576/~3,700,000 different combinations

=~.01557%, or ~1/6423 solves. Obviously an approximation, and probably some things I messed up or whatever...

Unfortunately his wouldn't happen in a WCA competition.

Fun video

Best reconstructor ever <3

I know I'm not Stefan, but:

24 possible one movers, 24 more from there, 24*24 = 576/~3,700,000 different combinations

=~.01557%, or ~1/6423 solves. Obviously an approximation, and probably some things I messed up or whatever...

As it can be solved with URF, there are really only 9 possible first moves: U U' U2 R R' R2 F F' F2. After that, you can only have another 6, because if you have U/U'/U2 first, then another U move next, that's only one move. So the chance of a 2 move scramble is (9*6)/(7!*3^6), or 54/3674160, or 1/68040.
