I think there is a timer called KR Timer which has substeps.

My question wasn't fully answered. Does anyone know the number of ELL cases excluding mirrors and inverses?

Yes it was...

He wants excluding mirrors and inverses. So I think that means [sexy, M'], [M', sexy], [lexy, M'] and [M', lexy] all count as just 1.
(if I've understood correctly)

What's the method on Square One which uses PLL? Could somebody link it please?

Does anybody know of a place to buy QiYi Square-1 spare parts? A corner snapped on mine and I don't want to buy a new one, even though it is my main event.

Thanks! Is there a link to the whole method?

Okay i need some help...;-) i want to know how to calculate numbers of different combinations on cubes and things like that... Can one of you guys tell me how or just send a link?? :tu

Ok, crash course in cube related combinatorics:
1) All pieces that are of the same type can be swapped.
ie corners swap with corners, edges with edges, wings with wings etc
2) number of positions a set of pieces can be in (only permutation)= n! Where n is the number of pieces
This is because if you have 8 corners for example, the first piece can go go in one of 8 places, the second in one of 7, the third in one of 6 and so on and so on
3) number of orientations:
Edges= (n-1)^2
Corners= (n-1)^3
wings= (n-1)^2
this is because all the pieces can be oriented independently except for the last piece which must be oriented in a manner dictated by the previous pieces to avoid flipped edges or twisted corners
4) permutation parity.
Essentially if you have an odd layered cube, divided by 2 to get rid of parity. This doesn't hold for even layered cubes (ie divide by 2 for 3x3, 5x5, 7x7 etc but not for 2x2, 4x4, 6x6 etc)
this is because corners and middle edges are interelated and must always have an even number of 2-swaps if both are present. However, this does not hold for even layer cubes as they have corners and wings (for 4x4+) and these do not need to have an even number of 2 swaps.
5) symmetries
There are 2 types of symmetries: rotational (includes Aufs) and reflectional. Essentially, every time you can rotate or reflect the cube along the central axises and still get an identical pattern of pieces, divide by 2.[/spoiler]
Hope this helps!

Thanks for the help ! :tu Can you give an example ?? just to see how it works...

Hi!
I never really used stackmat other than at comps,and I decided to try it, hence a few questions.
1) Afaik, Prizma Puzzle Timer supports the stackmat connection. Is it correct?
2) Are there any online timers that support stackmat?
3) Are there any Android timer apps that support stackmat (the phone has 3.5 mm socket, so why not)?

1) yes
2) cstimer does, but there is a special link I think (check the thread)
3) Idk but I don't think so

im trying to learn cll over the holidays and i find it extremely easy to learn the algs but i when i learn more than 2 a day i forget recognition does anyone have tips to get past this

One tip Anthony Brooks gave me was to make up names for the cases. That will help tie the recognition to the algorithm.
I like to tie visual clues to help with the first move:
With case A, the first move is to push the right yellow piece down with an F
With case B, the first move is to twist the matching pieces with an R2
Most of the time, the first one or two moves are enough to trigger the muscle memory. Even so, CLL recognition and execution took me much longer than OLL and PLL to become reflexive. Give it time.

I've been doing searches on this but I can't find anything, so I'm going to ask it here.
I know that for an average of 5 or 12 you take out the best and worst solve and average the rest. I'm curious what the convention is for averages of 50, 100, and 1000.
Related question: how does qqtimer calculate its averages of 100 and 1000?

Most timers (except Prisma, which does one time at either end) will remove the fastest and slowest 5% of solves, rounded up. So for Ao50, it will remove the fastest/slowest 3 solves (5% of 50 is 2.5).
