I'm going to use M2 for edges soon. I learned it a few weeks ago for 4BLD but haven't started using it for 3BLD.

Wait, you got a 1:02 with OP/OP?

Wow, that's a very impressive time. I learned M2 when I was barely sub-10 minutes.

New 3BLD PB - 3:54. I'm really pushing my memo and having some failures, but I'm also learning how to recover mid-solve. I've had success reversing botched execution and recovering forgotten memo by tracing the pieces already solved, and then using the remaining sticker letters to jog my memory.

I'm also getting much better at edge comms using M slice interchange, which really helps.

Edit: 2/4 MBLD in 32:59 - failures were because of 2 flipped edges and 2 twisted corners. Not really a success, but quite good for my first attempt with 4 cubes I think. 23 minutes of memo and 11 minutes of execution. I was experimenting with breaking into flipped edges and corners instead of memorizing the flips separately. Those flips actually worked - the errors were due to poorly executed commutators. The main thing is that I was substantially under the WCA 10 minutes/cube limit, so I can can afford to take a little more time and be careful with my execution next time. I was pushing my execution this time.

Edit: Untimed 3BLD success with UF/UFR buffers, instead of DF/DFR. It was less tricky than I thought it would be - I suppose that's because I am making up the comms intuitively. The edge comms did feel better, though the corner comms felt a bit worse because of all of the D layer insertions. I might switch just because it is a more popular buffer and there are more resources available. I'll see how similar the recommended comms are compared to the restricted set that I'm using.

4/4 in an untimed 3BLD relay (not MBLD). I was focusing on accuracy, especially with the M interchange edge commutators that I just started using. 100% accuracy feels good.

I used MBLD memo: edges then corners, using images for both and weak swap. I also successfully broke into twists, as well as handling an edge twist with visual memory before I began the rest of the solve. It's fun to pull out these techniques to help with accuracy.

I botched the execution of two comms - one edge and one corner - in the second cube. But I realized immediately and successfully reversed the comms, then executed correctly both times. It was very satisfying to see that cube solved correctly when I opened my eyes.

Edit: I also just succeeded with a modified version of my fully intuitive parity method (which gives me 5/5 successes, yay). I previously rotated the cube 90 degrees during memo when placing U layer pieces, then did a U' as my first move - this converts the cube to even parity. But it's difficult to do and not fun. This time, I instead just swapped the whole U layer by a quarter turn in my memo, and did U' as my last move. This was a lot easier and much less annoying. Obviously it's not suitable for speedsolving and it increases chances for errors, but it's fun to do.

I just finished my project to learn half of the 3-Style UF edge comms. Now I know all A, B, D, E, M, Q, and eight more M slice comms plus all their inverses. For the other half I only need a one move L/R setup to a known case. Now it's time to practice them a lot which is much more enjoyable for me than learning algs.

During the last five weeks I used the extra free time coming from the Corona restrictions to learn the second half of 3-style edges as well as another 15% of the corner comms. I'm really happy that this huge project is finished. I don't intend to continue learning algs for a couple of months. I just want to practice a lot and get new 3BLD PBs. Finally, I want to get back into MBLD which I enjoy the most but couldn't do for a while because my accuracy was way too low.

New 3BLD PB: 3:18.62.

I know I said that speed isn't my goal, and it's not - I don't need to be competitive. But the ease and flow of audio edges really helps me get in the zone. Getting stumped with a difficult letter pair interrupts my flow and makes memorization very irritating. I don't usually have time for a full MBLD session, so grabbing a quick 3BLD solve is great fun.

I'm still practicing MBLD techniques, even on single solves. Eventually the memo will get easier.

Audio edges are really hard for me now. How do they get easier for you? I find myself reviewing the corners and forgetting a lot of the edges. Also, do you use M2/OP?

Audio edges are really hard for me now. How do they get easier for you? I find myself reviewing the corners and forgetting a lot of the edges. Also, do you use M2/OP?

Audio edges are hard for me too - I have just started using them instead of using images for both corners and edges. Here are some things that make them usable for me:

1. Use a rhythm for the edge sounds - I got this idea from Noah Arthurs's tips. It helps if you are familiar with different poetic feet, i.e. iamb, trochee, dactyl. Using feet that fit the syllables makes them much easier to remember. If I know that a particular memo is dactylic or trochaic, for example, it makes it easier to recall the later syllables.
2. Use distinct sounds for the different letters. I use "ch" for C so that it doesn't sound like K or S, for example. I still get mixed up between V and B though.
3. Don't review corner memo after edges - go right into the solve. I review corner memo once right after doing it, then memo audio edges, then do the solve without reviewing corners. Audio edges are designed for speed, not accuracy. WCA regs take the best of 3 times, so top cubers use methods like audio edges that are fast but inaccurate - you can have a DNF 2/3 of the time and it doesn't matter for your competition results. Graham Siggins mentions this in his 3BLD walkthrough. So, sometimes you will forget corners or mess up edges when using audio edges. If you want 100% accuracy, use MBLD memo techniques.
4. Audio edges need fast memo, so you can't really use them until you are very familiar with your lettering scheme. Having to pause during the memo to find pieces or think about lettering will make you forget the audio memo. You need to be able to deal with cycle breaks and other memo problems seamlessly. If you're still working through memo basics, stick to images for edges and corners.

As for my method, I use intuitive 3 style. It's super easy to learn. I am going to make a guide for learning intuitive 3 style, since there aren't really any resources available. You can start by learning the different insertions that go with a particular interchange layer: you need 4 edge insertions and 4 corner insertions for each interchange. If you start with only one interchange, you will be able to solve all cases with 1- or 2-move conjugates.

This is my first blind method - I never learned other methods because I prefer intuitive solving to algorithms.

Wow thanks! I think this is really going to help me in the future.

Wow thanks! I think this is really going to help me in the future.

Great, I'm glad you found it useful. I just experimented with using images for edges and audio for corners, then executing corners first and edges last. This makes the audio memo a lot easier, since I have to store less information in audio, and the larger chunk of information is stored with images. I had a success my first time doing it, and it was a lot easier than audio edges.

It should also make parity easier, since I can just use weak swap when memorizing edges, then do a parity corner swap during corner memo, which will save a conjugate. I will just be able to execute my parity alg at the end of the solve, since all 4 pieces will be in the correct place already.

Come to think of it, I could use weak swap on corners if I memorized corners first too - I will try that as well. But if I did this in MBLD, I would have to memorize parity separately - currently I just know that I have odd parity if there is a single corner target at the end. Noah says that he uses an image of blood to indicate parity - maybe I will try that.

Edit: Yup, this works for parity and eliminates the conjugate. I will try this as my main method for a while and see how I do. I think it will work well, with the added benefit that I will memo in the same order for 3BLD and MBLD - the execution will just be swapped.

FYI, I think the reason most people do audio for edges rather than corners is literally because it's a larger chunk of information. Audio doesn't stick as well, but memorizing edges with images rather than corners will waste more effort reviewing. This is hard to explain but what I'm trying to say is that if audio works, it's better. If it's too much to memorize with audio, images work better. Audio works for edges so it's generally better. On the other hand, because of the way you do parity, it might be better to do what you described. I (and most traditional 3-style solvers) know all the parity algs for UF-UR + UFR-XYZ so I can do one alg with no setups regardless of the last corner target. Since that's not the case for you, it could be better to do corner audio. I'm glad you're having a good time exploring 3BLD regardless!

 

[dudefaceguy]

if audio works, it's better. If it's too much to memorize with audio, images work better.

This is a great way to put it. I'm still too slow for audio edges to work reliably, so audio corners is a good intermediate step for me.

I am indeed having a lot of fun exploring 3 style and finding techniques that work for me. I've gotten several sub-4-minute solves (which is good for me) with this new technique, so it's definitely helping to improve both memo and execution. Most importantly, it's a lot of fun.

Edit: Sub-4-minute average of 5, including a new PB of 3:18.205 (with parity), basically tying my prior PB which used audio edges. My accuracy is also way better - that prior PB was a fluke during a memo-pushing session where almost all of my solves were failures. Audio corners, weak swap, and swapping corners really work well for me. I'm very happy being at 4 minutes.

Im a new blind solver and have only gotten into the event in the last few weeks due to quarantine and I've just had this thought I want to share. I am currently studying french at school and I was wondering if doing memo in 2 languages would have some sort of benefit? I dont have that great of a grasp on bld since I only have 3 successes at the moment so if this sounds dumb that's because it is. I think it could be used for big blind and Mbld for doing different rooms and such.
