Can you explain 'audio'?


Melody, Do you know this trick: when two edges are flipped set them up to UF and UB and do (M' U')4 (U' M')4

I believe audio is just stringing your letter pairs into one or two nonsensical words. For example FE CL RT LG
Might be memorized as Feckel Ertelg.
It's just sounding out the random letters.

 

[moralsh]

Audio is remembering the sound of it, Noah Arthurs likes to repeat a bunch of syllables and I just pronounce the letters in groups of four. Is a fast way of remembering something for a very short time.

I just say in my head Gfcv rtud bql like three Times and execute it. I usually can't remember the audio once I've finished, but serves its purpose

Yes. But it's hard to get myself motivated to practice BLD. If I really practiced it, I would probably be decent at it. Is there a BLD race thread? Sorry, just wondering aloud. The fastest I've gotten is a sub-4 single but that's not with much practice.

I was using M2/OP but I would need to refresh a few of the M-slice algs. I think I stopped practicing because I wasn't decided on my memo system. I was trying to figure out an even more effective way of memorizing if possible though I like audio and some letter pairs. Specifically I wanted to be able to use notes in a scale like in music. Hadn't figured out how though.

I like to read this thread to keep motivation to practice, because I'm around sub-25 for a half of year. It looked like I stucked. That's why I keep practice 3bld and started 4bld. I do just few 3bld per day and after 3 months with OP/M2 it's quite easy for me to make 3bld solve. My best single is 2:55.

Melody, Do you know this trick: when two edges are flipped set them up to UF and UB and do (M' U')4 (U' M')4

There are few ways to flip edges. I think your alg works ok but to flip UF and UB I use alg Maskow showed in his tutorial: U2 (M' U M' U M') U2 (M U M U M). One can modify it to flip UL and UR: U (M' U M' U M') U2 (M U M U M) U. The second alg flips UF and UR: R' (U2 R2 U R' U' R' U2 r U R U' r'). Of course one can modify the third alg to flip UF and RF: (U2 R2 U R' U' R' U2 r U R U' r') R'.

Using these two algs and its modifications makes flips easier, because setups are shorter. And of course you can rotate cube to avoid setups at all.

I'm terrible at keeping up with race threads these days but I will if I remember.

Ok... I've made a start. The 4x4x4 race solves will be my Wednesday practice session and I'll try to fit in a second 4x4x4 session each week.

I hope you guys will join me in the quest for 4x4x4 improvement!

Specifically I wanted to be able to use notes in a scale like in music. Hadn't figured out how though.

When I read this I first thought: 7 notes, seven corners in a cube if you exclude the buffer, then we have sharps and flats for orientation, cool, then I remembered there is no E sharp or D flat, oops
then I thought about using two octaves, that will make 24 notes which is enough to play with both for corners and edges.

Another options is using chords, Seven notes, seven targets, Major if oriented Minor for one orientation and any other for the other, It could work somehow.

Yeah 4x4 is fun so I will try.

My experiment to see if it improves my 3x3 times got off to a bad start though. My 3x3 average last night was around 21.5 and that's down from 23 or so for the first 20. After a couple of days on 4x4 it felt like I had to turn flat out on 3x3, and also my lookahead had got worse. I think on 4x4 I just can't turn the puzzle as fast and therefore have more time to lookahead, and when I go back to 3x3, neither are fast enough.

Oh, great! Didn't ever even know this new 4x4 race thread has been up. Will definitely join.

Too many octaves is harder to sing and also may have very big leaps. Besides knowing which corner, you have to know which side. Since each corner only has three possible sides, U/D, R/L, F/B you could have three different added detail (don't know what detail) to the note the know the side. I'm not sure if rhythm (length of note) or something like that could work. I also didn't want to use sharps and flats (besides that it doesn't really work for some notes) because then you might get some weird intervals.

Awesome! The thread was actually getting dead a couple of rounds ago, so I am glad that you guys want to join in. I am working on getting sub 1:15 right now, and I really want a sub 1:00 (PB is 1:01.xx)

Looking on the bright side your 4x4x4 / 3x3x3 ratio is better now.

Maybe you were just a little rusty and started rushing / turning too fast rather than finding your tempo and solving smoothly?

Another thing to remember... it's not long ago that you'd have been pleased with a 21.50 average. I'm sure you'll be close to 20 again in no time!

I figured I'd get the ball rolling but I was surprised to get PBs after yesterdays shameful performance.

Ao12 from 02:20 down to 01:58 in 24 hours.

Yes I'm not complaining about any of it, just theorizing then making observations about how 4x4 practice affects my 3x3 times.

Actually a few months ago I did some sessions of F2L practice on 4x4, with the thought that being compelled by the puzzle to turn slower might help train lookahead. My F2L is mostly smooth and pauseless on 4x4. At the time I was averaging about 10 on 3x3 but my average on 4x4 never improved beyond about 15 despite almost no pauses. In other words, my tps is too slow even for effective lookahead training .

Conclusion: I need to sort out tensions and lube and drill tps on 4x4.

I just saw that your most recent ao100 was 20.98. I thought that you were still in the 21's. Good progress.

Yep, that was a hard-won 0.02

 

[Rocky0701]

I have always wanted to do a full average of 1000 over the span of a couple of weeks but I am so unpatient. I got to like 560 solves a couple of weeks ago and it was 19.99 at the 500 solve mark but then the next 60 solves had a ton of fail solves that brought the average down a ton so I rage quitted haha.

 

[MarcelP]

yeah, I will. I just had a 1.48 average in this weeks forum competition. I did not practice 4X4 at all, but did many 5X5 solves.. Dropped 5X5 from 9 to 6 minutes.

I had not touched my Rubiks cube since competition. Just did an Ao50:

yeah, I will. I just had a 1.48 average in this weeks forum competition.

Didn't you say you were struggling to get sub-2 around a week ago?

Dropped 5X5 from 9 to 6 minutes.

Nice. I haven't timed myself at 5x5x5 yet but I know it would be very slow!

 

[MarcelP]

Didn't you say you were struggling to get sub-2 around a week ago?

Yeah, still I am. There was also a 1.27 in there. I think it was just a lucky average. Most averages are around 2:00

 

[Schmidt]

Lucky for you! I had a 2:05.xx 2-3-4 relay this week, so I was hoping you didn't do so well

 

[mark49152]

My AoChuang arrived. Wow. I think I may get into 5x5 at last...
