I can't seem to find the video now, might be because I'm on a restricted YouTube account because its my school account. I will have to dig deeper.

Sorry, I meant the video I had seen before. I started watching that video but didn't have time to finish it.

what you think is better?

1. yau or hoya for 4x4?
2. yau or hoya for other big cubes?
3. why?

please elaborate

Better is pretty subjective in this case. Both methods are good and it just depends on which you're most comfortable with. I use Hoya and would argue that it's better for me. Lookahead on cross edges is much easier for me with Hoya and also transitioning between steps flows much nicer. I think it's a little less efficient than Yau but that's the trade off and I think it's worth it.

For this question you often see both sides making the exact same points.

The general consensus tho seems to be Yau for 4x4 with 5x5 being a no mans land and Freeslice for 6-7.
Why?
4x4 has 24 (X) Centers and 24 Dedges. Centers are paired easily even with slight restrictions but Dedges need some time. So for 4x4, the Edge Pairing method you are most comfortable with is what likely will make you the fastest. From what I see, Yau 3-2-3 is by far the most popular.

J Perm made a statement once saying that one should stick to the same method for all big cubes, which I disagree with. 4x4 and 5x5 are, by a small amount, easier in every way than 6 and 7. So it makes sense to use an advanced method suited to their properties. There surely is a good 6x6 reduction method to be found but relatively little research is done so most stick to freeslice.
But, since there is a shared opinion that Yau, Hoya and Freeslice are equally good in 5x5, you'd logically want to use what you use for 4x4.

Freeslice for 6-7.

When you realize that WR2 uses Yau

Hello. Im curious on how do i use the database query of wca statistics. I know you need knowledge in sql so i might watch a tutorial with that.

 

[NmeCuber]

Oh nah

You can also download the whole database and analyze it with R or Pandas.

I used pandas a lot but I never used R, do you suggest any good tutorial to get started with? I want to try out

R takes a little bit of time to learn in terms of syntax. I learned mostly in college and reading Stack Overflow. I would recommend learning tools like dplyr in the tidyverse or data.table since they're easier to use than base R. But I guess it's more productive to stick with pandas since all the basic statistics tools are in python and R both

thanks for the tip!

I read a post these days about a timer.

The user said that he stopped using cstimer because he had to import and export his times. Then he said he was using some other cubing timer.
But I can't find the post nor remember the name of the timer

if someone could help...

EDIT: I think I found it. it was cubedesk.

OLL 18: https://speedcubedb.com/a/3x3/OLL/OLL_18
Dot Cases have those half Sune-Sledge-Insert triggers, such as this alg for OLL18:
R U2 R2 F R F' U2 M' U R U' r' with M' U R U' r' as insert.
I noticed that R U R U F R F' U2 M' U R U' r' solves this case with y2 angle (with the "Su" instead of "ne" of "Sune")

I was just surpised, that this alg wasn't there. Shouldn't be all common trigger combinations be noted?

 

[Deleted member 36445]

I don't get what you mean by that

 

[Deleted member 36445]

guys, quick question

where can I found the best algs for skewb and pyraminx?

 

[espeed]

I don't get what you mean by that

I'm sorry, my English can be weird sometimes.

Many OLLs are (RUR'U or RU2R') + Sledge + Insert Pair. I just expected every possible alg of that kind to be listed on speedcubedb and was surprised that R U2 R2 F R F' U2 M' U R U' r wasn't there.

I think it shows that it is always good to try things out.

That's the one I use and the first in the list on speedcubedb
Even with a video

some time ago kirjava made a document showing the solution to all the ollcps with just trigger combos
he even learned all of it and could solve OLLCP every time

the site is off, but you can access it on wayback machine

OLLCP (hax) - Speedsolving.com Wiki

All puzzles, all the time. Come in and discuss the latest puzzles, techniques, competitions, learn to cube, and more!

web.archive.org

some years later he posted a method to solve the last layer with two looks. it was something like solving one block on the last layer then solving the rest

and he used the same technique, he combined common triggers and short algs to find all the solutions

but I can't find the page. if I'm not mistaken it was called the flex method

you can find on his github but I can't find it either. =\

kirjava real name is thom barlow

EDIT: After some investigation I found the method. is called duplex, not flex
