Turn a skewb 60 degrees, what's the angle between the 2 touching square centers?

Someone better check, but I think...

Consider square has side length 2
By Pythagoras, diagonal from centre of square to corner of square is sqrt(2)
So distance from centre of cube to centre of square is also sqrt(2)
So triangle formed at centre of edge of square between centre of cube and centre of square has angle arctan(sqrt(2))
So angle between two squares when edges touch is 2*arctan(sqrt(2)) in degrees = 109.471221 degrees (via google calculator)

Is there any metric that:

-counts M as one move
-counts R2 as two moves
-does not count cube rotations

Are they? I thought they would just be skipped.

I thought unrecognized characters were just ignored? Like 2013KOSK01

I don't know the policy, but I know that I've seen replacement with A before.

Does anyone fast do this for OH?:
- Rouxblock
- Finish cross with <r, R, U>
- Finish F2L/OLL/PLL as normal

Is it not because the letter can't be skipped (that weird thing is the last character)?

I've done some tests with this and despite spending a lot of extra moves/time in the first two steps (I'm really bad at them) most of my solves are sub20 and I've had some sub15 singles. It may have potential.

 

[Robert-Y]

I will try, thanks for suggesting

 

[Robert-Y]

I'm not great at making the first block and I find building the rest of the cross a bit difficult, but surely this is worth doing when the first block is easy.

I just tried this. I consider myself as relatively fast in OH (15 avg at home) and relatively good in blockbuilding. These are my results:
number of times: 30/30
best time: 12.37
worst time: 21.69
best avg5: 17.61 (σ = 0.34)
best avg12: 17.75 (σ = 1.58)
session avg: 18.20 (σ = 1.40)
session mean: 18.08

The 12 was nonlucky. I guess I would get at least as fast as with CFOP using this method.

I used to do this, but my blockbuilding was awful back then. It's probably best to be method neutral between this and CFOP, since the block isn't always easy.

What do you think about orienting edges during cross so the F2L is finished 2-gen? It could be worth it to just orient the F2L edges if they're in a nice position.

ZZ?

Has anyone done a zbll time attack? I would love to see it.

Is Hyeon Kyo Kyoung the fastest ZZ user?

 

[Bilbo7]

I've got sub 40 in 4 months so pretty good!

You think he used ZZ?

Also, from his videos of solves it looks like he does indeed use ZZ.

 

[Robert-Y]

However: https://www.youtube.com/watch?v=Wo0P-wEAvbQ

So I doubt he used ZZ
