For 2x2x2, I don't get how many moves the minimum scramble is in competition. In the WCA regulations, it says "random position" which I don't get. On the scramble program, it gives me http://www.worldcubeassociation.org/regulations/scrambles/scramble_cube_222.html which has 8 moves automatically, is this correct? And is the actual scrambler they use? Thanks.

If you look in the page source for the url you gave, you'll find this:

// Alternative mixing function, based on generating a random-state (by Conrad Rider)
function mix2(){

It's generating a random state for the puzzle, then finding a solution for that state. The number of moves doesn't matter. I'm not sure why you're saying "has 8 moves automatically"; the number of moves varies from scramble to scramble, and the default setting for minimum scramble length is zero, so it doesn't look like that's where you got it. It's the scrambler I use when generating scrambles for an official competition. I also used this code (copied separately and incorporated into a script) to generate the scrambles for the weekly competitions here.

In CFOP it would be Cross=7, F2L1=7, 2=7, 3=7, 4=7 =35 move count for first 2 layers.

I am unsure what you mean by this. First of all, the cross can sometimes require up to 8 moves. Second, where are you getting the 7's for each F2L pair?

Thank you very much for the explanation. I only counted the moves for the first scramble I got, and the others, just by a quick glance, looked the same length. So my bad on that, sorry.

I took a random F2L cheat sheet and counted:
4 + 4 + 3 + 3 + 8 + 7 + 8 + 7 + 8 + 8 + 8 + 11 + 8 + 8 + 8 + 8 + 7 + 7 + 7 + 7 + 5 + 5 + 11 + 9 + 8 + 8 + 7 + 7 + 7 + 7 + 7 + 11 + 8 + 8 + 8 + 8 + 0 + 11 + 11 + 11 + 11 + 12 / 42 = 7,5952380952380952380952380952381
So it should prob. be 8+7+8+7+8=38 instead

I see. That probably isn't the best way to figure out F2L movecount, considering how people solve differently and don't always use what could be considered the most common 'alg', and I'm pretty sure many of those aren't optimal. I don't have any tips on a better way to count, though....

 

[Schmidt]

It is more of a guideline instead of a bottom line. You could get unlucky and have a solve with 11+11+11+12 F2L but as you get more XP you would avoid those if it wasn't the last unsolved slot, or you would learn advanced F2L tricks. Sub 40 MC for C+F2L is a nice goal in every solve.

What's a PLL Time Attack?

 

[RyanReese09]

Do all the PLLs, time yourself how long it takes you. Do them in any order you wish.

are you allowed to just watch wca competitions and not compete?

 

[emolover]

are you allowed to just watch wca competitions and not compete?

You can just watch if you want to. I dont see why you would not compete in a event if you can solve it.

 

[n00bcub3r]

its cuz my times r like 2 30 cuz i just learned how 2 solve

 

[Julian]

are you allowed to just watch wca competitions and not compete?

For most, yes. Although, sometimes the venue has an admission fee (science centres, etc.) that you'd have to pay to watch.

Going to a competition is not about how well you do. It is about having fun and meeting other cubers.

 

[cuberkid10]

For Marietta (which I assume you're talking about). If you want to come and not compete, you probably can. If you wanted food though, you might have to pay.

How many pieces total are in the shengshou 4x4?

 

[Riley]

How many pieces total are in the shengshou 4x4?

24 centers, 8 corners, 24 edges, 1 core, 22 small internal pieces, 12 big internal pieces. Just by memory, but I think it's right.

What means "plus 2"?

 

[Clayy9]

What means "plus 2"?

+2 (seconds) is a penalty given to your time if the given puzzle is one turn away from being solved after you've already stopped the timer.
