Solving the same scramble

[SamKennedy]

Is there any value in solving the same scramble? I just tried it out of curiosity and got my times down from 39.85 seconds to 23.54 after 3 attempts.

I was thinking practising like this would improve my accuracy with moving the cube quickly, as well as increasing my efficiency and ability to look for the best solution.

No it's a terrible idea. You're quicker because you already know what's going to happen... traditionally in cubing your speed is determined by how quickly you can solve a randomly scrambled cube... doing the same scramble all the time wont provide you the skills needed to solve a random cube (such as looking ahead).

It is a fun excersize to determine you theoretical speedlimit.
After enough repetitions you will have 100% look- (know-) ahead and then it is all about execution speed.

 

[Godmil]

Darn, ninja'd with my second point.
Yes I guess it does have a little bit of value... it kinda suggests that if you had really good look ahead then your average would be more like 23 seconds... makes it seem worth practicing doesn't it?

I'm no pro, but I guess it can help if you feel like you experienced difficulties with a certain part of the solve... Let's say you get a case you have not seen before while doing your F2L, maybe it can help you develop a proceidure for it? Does this make any sense at all?

I only do it when I need a self-esteem boost My times go from like 17 to 10!

Yeah, the solve essentially becomes one algorithm. And who practices algorithms? Right?

I like doing this as an exercise, solving each scramble ten times and counting the best result.

Hey! I practice algs...

I guess I just don't have the time to practice all 43,252,003,274,489,856,000 algs.

I guess I just don't have the time to practice all 43,252,003,274,489,856,000 algs.

You only need about 1,300,000,000,000,000,000 (bonus points if you can guess how I got that number ).

The point was that repeating the same solve can help finding and fixing weaknesses, just like when repeating algs.

sometimes when I dont use an alg to scramble, I scramble the cube to the exact same scramble like three times in a row. its really weird. because theres this one scramble that my fingers just do from time to time, and its probably about 20 moves long, but I can usually get a sub ten with that scramble, just because Ive accidentally scrambled my cube to that scramble so many times. anybody else have this? (sorry if this is going off topic...)

 

[Godmil]

Fare enough about finding and fixing weaknesses... though that's not why I repeat algs.
Where did you get the number from?

Well, if you had a cube, and did a y or a y', you'd have a different solution. So I guess you could divide that number by however many ways you can hold a cube. I'm not sure if that's how he got it though.

 

[Stefan]

Where did you get the number from?

1. You can save a factor of about 24 because of cube rotations.
2. You mainly need to learn algs for the cases that take 18 moves. The easier cases all have algs that are part of an 18-mover alg, and the harder cases are rare.
3. Looked at the bottom table on http://cube20.org/ and calculated 31/24.

When I was learning full OLL I invented the "Double Kill Scramble"

I would solve the F2L in different ways to see what OLL that made and learned that from the cheat sheet, as I thought that seeing that OLL in a "real" scramble (instead of just alg. reps.) would make it stick faster. I don't know if it helped, but I'm know full OLL now.

Disagree.

 

[JonnyWhoopes]

Disagree.

Give an example please?

Just think about it... For most of the 18moves positions you have a lot of different solutions. You can easily avoid a case.

What? Avoid what cases?

Avoid a 17moves case.
