Nice @h2f!

I've been trying to refresh my memory on blind solving the last couple of days. It seems I'm back at the 1 mistake/solve stage. No complete successes, but lots of solves with one mistake. Mostly memo mistakes, like missing a flipped edge, forgetting to twist corners or skipping a 3-cycle during execution. Good thing is that the execution part otherwise seems pretty good. Only twice have I opened my eyes to find the cube a complete mess, which is the result of execution errors.

The PLL algs I've learned help a lot. I've already used both J-perm and Y-perm for some parity cases. Now I should memorize which direction the A-perms move the corners. Those can come in handy for corner cycles. With UFR as my buffer, I also need to explore what else they are good for, for example the truncated version U R' D2 R U' R' D2 R is a pretty nice commutator I wouldn't have thought of otherwise.

I've filmed (I should have done it from the left) a good solve (for me), it was 2-look, for OH I still don't use half of the CMLLs I know. Tell me how many weird things do you spot in that solve

Solve starts at @0:19

Non? I like your turning style and LSE looks fine.

I dont know what A perm you use, but for me it was the eye opener when I realized that my A perm is just R2 seutp and comm with x rotation: UBL - DBR - DFR. This case a use a lot for down targets. So drill it and I'm sure you will find it to be very usefull.

Have you tried redo scramble to see what was bad? I do this a lot for example to drill algs.

Doing an L2 z2 to build the SB also on the left is probably questionable.

I use l' U R' D2 R U' R' D2 R2 and x R2' D2 R U R' D2 R U' R for A perms. With UFR as my buffer, I can also use those without the x rotation and skipping the first and last move, like mentioned above, to cycle UFR-BDL-UBR in both directions. Interesting idea to use it for down targets. In my case, I'd have to do B2 instead of R2, which is not quite as convenient, but I'll keep it in mind.

Most of the time I've been able to figure out what went wrong, if it's only one mistake. If the cube ends up a complete mess, I suspect I would need to film my solves to see where the mistake(s) was made.

I dont think it's bad in OH. If it gives you easier moves, it's ok. I've started doing it too.

Nice solve, David. The problem with OH amnesia is universal, I still don't use more than half my OLLs and the PLLs took an effort to be relearned for OH.

Today I recorded a 14.08 full step solve and... you know what? It was a +2

 

[newtonbase]

Have checked with work and will be able to go. Hopefully see you and Mark up there.

@Selkie, registration is tonight if you haven't seen this yet and are interested.

I've registered for more events than I plan to do but decisions can be made later. There's a baby due in the family that weekend so I may not be able to go at all but I'll practice as if I can.

 

[Logiqx]

My current Ao5 for these are 7:52 and 11:25 respectively. I'm sure that with your 3x3 skills relative to mine, you'll be able to better that in short order. I do enjoy both and the Weekly Competition has been a big motivator for me picking these up. Have fun!

6x6 times have been improving with half a dozen solves a day... currently 7:24 Ao5.

Edit: Guess I'll be ready for big cubes when I finally make it to a competition!

Bit quiet today. Hope you're all still alive.

Here's a new game and challenge. 5x5 five move scramble. PB ao12 = 28.93.

(Rules: do the first five moves of a computer scramble, toss and spin it, no inspection.)

 

[phreaker]

Alive yep. Actually gave a co-worker information about how to learn to cube.

My OH times are dropping.

My Weilong GTS needs to be relubed, it is so fast, I'm dropping it. It is also chewing on my thumb like a mad puppy, so between that and my left pinky bothering me a bit, I may be due a few days off to let my hand heal, maybe some 2H cubing once I fix up the GTS.

Maybe order a second if my OH and 2H setup is different.

Yes. I'm in OH. I did a practice yesterday around midnight... I'm sub50 ao100 right now and finally beaten my previous ao12 pb by 0.36 sec. But still I have no ao5 sub40 (40.32) so far.

Well that was an odd average:

3:40.99, 16.84, (5:00.48,) (12.19,) 20.05

Ao5: 1:25.96

Scrambles:
1. Dw2 Bw2 F Uw2 Bw2
2. B' D Uw' F2 Uw'
3. B2 F2 Dw2 Fw Dw'
4. D2 Uw U' L' Rw2
5. Uw' Rw2 R2 Fw2 D

Interesting though @mark49152, cheers for the idea.

We should probably use the same scrambles since they make a big difference to the outcome. I had a cool 7 second solve, several 12's and some twenties but various screw ups taking several minutes. I didn't complete an Ao12 as I restarted after 2 fails and after 3 failed averages, I decided to get back to what I was supposed to be doing. Fun activity mind you.

 

[newtonbase]

I meant to do 5 but lost track
29.27, 26.60, 24.23, 7.00.63! 19.71, 13.67

 

[Rastinha]

That sounds like fun, I'll try it on one of my breaks today

I do use bins and think they help. They don't block out all noise but they muffle it enough that it feels like I'm in a world of my own, like an isolating effect. I can't say they'd give an immediate improvement but they're worth a try.

I definitely memo faster with noise reduction, it helps me focus on the blindsolve both while putting them on and while memoing. I don't use them at home, though.

It sounds like headphones may be what I need. Maybe even if they aren't great, they will at least have a placebo effect and I'll feel more confident and focused just because I'm wearing them. Really want an official 4BLD success now, especially since I've been doing so well at home (with successes, time is still way behind you guys), and still need better official 3BLD and MBLD too.

 

[Rastinha]

I used swimming ear plugs for my first comp, the putty kind that mould into your ears. I found they helped me concentrate since our BLD rounds were held during the lunch break and it was quite noisy. I don't train with them though, and headphones/ear muffs would probably be more convenient as if the seal on the putty comes away a little it can be distracting. But that's all I had at the time!

I bet this guy was glad he had bins.

Haha, I played twice and I'm quiting. Might do more but I'm tired. Got 14.70 and 6:52.32 (a good minute over a normal solve!). I spent a long time thinking I could restore the second one, then when I gave in and built my centers I went to edge pairing not using Hoya like normal for me. So it took forever. Maybe another time.
