For OC (RD - UF) I use setup U2 but I must switch to direct insert y' [U M' U', R2]. For PL I do z' rotation because I dont like E/E' moves. It goes z' [M', U L' U']

I'm looking for a group or type of comms to tackle first. For corner comms, I learned U interchanges first. It makes it more systematic, so easier to remember and faster to think on the fly, for me. I'm no good just learning hundreds of unstructured algs.

I learnt corners with a systematic method like you. For edges it was without any order. Just adding what I've figured out - like "how can I do it directly not with M2?" I'm sure there are grups of comms but I dont know how to group them. I think it's good to start from FU/BD and follow with interchange edges without setups like LU-LD or LU-LB because with adv M2 you know the cases like UL-BL.

Yeah I should learn to use FU/BD. For the rest I might work through by brute force and see what patterns emerge.

So in what order would you guys recommend I start learning? It's my next project once the UKs are out of the way. I'm saving 4BLD until I have a MBLD success.

I've started with Noah Arthur's tutorial. He said RFD (target in OP) to all targets. Next FRD and DRF to know whole one corner. Next I did all U targets and steps by steps: L, F, R, B, D but when you know more the less you need to know.

Looks like a good place to start. Thanks

I have 6 comms plus inverses already!

Oops. I forgot to check the transparency. What brought it to your attention?

Visualcube is semi-broken at the moment and only generating SVG. I used some online tools to convert to PNG, generate sprite sheets and finally optimise the compression. Somewhere along the line they must have lost the transparency.

I don't use white as default background colour, for me it looks like this.
I know of atleast two other visualcube servers:

When I'm practicing with @JanW trainer my average speed per pair is 2 seconds. If there's 7 pairs in average solve it gives 14 seconds for edges. I think it's worth knowing and using.

Wow, that's really good! Back when I was practicing with the app, even the fastest were something like 5-6 seconds/pair. I should use my own app more often. But there's so many events, so much that needs to be learned, so little time...

I've done my first attempts at timed 4x4 solves. Average about 2:30, best so far 2:14. I have no idea is this is good for a beginner or not.

I'm about as beginner as they get on 4x4, picked up a G4 about a week and a half ago and no previous 4x4 experience. 4:16/5:07 best single and ao5 so far, using Yau. I've also done a handful of solves trying out Hoya; I like them both but I'm sticking with Yau for a little while. Most of my slowness is building centers and connecting edges. Also, probably still a 40% chance I forget to slice back or otherwise do something to botch it. You're not far from typical cutoffs!

 

[muchacho]

I was averaging 2:15 at 4x4, stopped 4 months until today, and even after doing a lot of solves I'm barely sub-3, so I have to say 2:30 is quite good.

Thanks for the heads up. I've fixed all of the images now.

Edit: Even better now... thanks to ImageMagick.

... My .htaccess also ensures that resource files (css, sprites, js) are cached long-term by web browsers. The resource files have a version number to allow for this caching approach. ...

This falls under best practices but I think it may be a case of premature optimization. You're already using relatively small sprites and the simplicity has limited the number of assets over the wire. The downside of caching is when it does cause trouble it can be quite difficult to duplicate and track down, the behavior on the client-side can be baffling. I'm sure your cache-bust scheme mitigates that but I'd personally just leave that to the browsers to decide unless/until you're addressing a real benchmarked bottle-neck.

That small opinion aside, I love what you've done and how portable it is.

Yes, that's my intention. I want to do all of my LL algs plus F2L, F2B, Ortega and big cubes so I'll do a menu system.

I also know a number of intermediate (2-look) alg sets like CLL+ELL, CPEOLL+2GLL, LLEF+L4C which I plan to do after PLL since they are only small.

Definitely looking forward to the expansion, especially F2L. The algs I've picked up from you so far really suit my turning style and I'm wagering you have a pile of exception cases based on destination slot that will make me very happy.

That's pretty good! I think I was 4-5 minutes for a while. Then stayed over two minutes for quite some time. I'm still just between 1:30 and 2:00 now, only one sub 1:20 so far.

 

[teacher77]

I got a new PB for a 10+ average : 30.09 s !! Almost there ! Here's the breakdown :

1 23.57
2 27.99
3 27.62
4 28.02
5 37.87
6 29.21
7 32.49
8 28.89
10 32.90
11 31.13
12 28.25
13 28.16
14 29.75

EDIT : also, it's the first time I get two "sub24" solves in the same day.

Mike: I've just had a quick look at your algorithm links, all I get is a white page telling me javascript needs enabling. It is enabled, but I guess there's more than one type of javascript....I even tried you 'homepage' to see what other algs etc you might have, and got a 403 forbidden. Do I just wait until I get on a better 'puter?

There's no home page yet... just direct links to specific pages.

What OS / browser / version are you using?

 

[SenorJuan]

A PM exchange with Mike suggests I am using the wrong kind of coal in my computer's boiler, and the pressure is too low. (HeHe).

Back to cubing: a guy I know via my work was rather impressed by my mirrorblocks that I had sitting around in the lab, and he asked me to e-mail him my recommended UK puzzle web-stores .... Marty's shop should certainly have enough to keep him amused. Assuming the excess of Oriental names doesn't overwhelm him.
And I gave a demo of unsighted mirrorblocks solving (with commentary) to my 1980's-solver friend last week, I think he enjoyed it, and the low price-tag may result in a purchase, maybe of the 2x2 version.

Oh? Guess I'm pretty happy with my results then. Maybe I'm not that much of a beginner after all. I got my first 4x4 about 10 months ago and recently purchased my 3rd cube. Have been playing around with the first two every now and then since I got them, but never timed my solves. My latest 4x4, the KungFu/CangFeng is in a league of it's own, so much easier to work with than my G4 or the previous Yuxin.

I tried a 3x3 Ao12 on the KungFu 4x4 to see how much the cube is slowing me down compared to a good speedcube. Ao12 was 33.44s, about 33% slower than my latest 3x3 Ao100, which doesn't seem too bad to me. I even managed one 25s full step solve.
