3/4 in 32:07. The failure was because of 2 flipped edges. I successfully broke into all of the flipped edges from the scrambles as part of my normal comms - these two flips were due to an execution mistake.

I tried doing the last cube as a 3BLD, which worked quite well. The other 3 cubes all had odd parity, and I executed successfully using my new technique of weak swap on edges, then swapping 2 corners to avoid a conjugate before my parity alg. I used blood as an image to indicate parity, which worked very well.

This solve also marked another visit from my favorite character, the mischevious anthropomorphic chicken nugget (NG). I always enjoy his antics whenever he shows up. This time he was hit by a train.

Do you guys have any favorite recurring characters in your memo?

Edit: untimed 4/4 success - probably around 40 minutes. If I just concentrate on accuracy, speed will come in time. All 4 cubes had parity, and I executed successfully using my new pair commutator technique.

I just wanted to see how fast I am since I haven't done a 2 cube attempt in a while (2019-45 fyo).
It was the 2nd attempt and it's actually not bad, pretty good scrambles though.

another MBLD attempt, another huge disappointment:
6/10 in 54:20.07 [38:40.71]

DNFs:
Cube1: 2FE - somehow memoed EF as my last edge targets instead of DL
idk how I missed that rip
Cube3: 4E4C - 1 move yeeeee
Cube4: 4E4C - guess what? ... another move
Cube8: 3E, 1 flip and 2C - had a pop during edges

8/10 DNFs of my last 3 attempts were exec errors rip

Oh I'm so glad this thread is being used a bit more! :)
I broke a very big barrier today, getting my first sub 2 avg/cube!
ResultTime[memo]Pointsavg memo/cubeavg exec/cubetotal avg/cubeDateErrors
22/2855:12[36:45]161:18.75(PB!!)39.53(Very good hehe)1:58.28 (PB!!)1 May 2020C8: messed up edge memo a bit.. C11: inversed TK corners. C13: recalled/executed MQ instead of MJ (both are people who I can't really picture well, should change one of the pairs). C14: memo error involving Weak Swap, fair enough. C15: inversed ND corners. C26: recalled FG and TM wrong way round.
As usual my accuracy isn't pretty, and up to now (just shy of 30 multi attempts this year) I have only scored 2 results on my top 10 list. I definitely need to clear that list of 2019 entries and fill it with 2020 ones. (also maybe I can try get to 120 attempts this year, I'll exclude attempts under 10 cubes I guess)
Stay safe!

4/6 for my first 6-cube attempt. Unfortunately I messed up my timer, but I also took note of the clock and I finished in almost exactly one hour. I spent about 35 minutes on memo. Looks like I messed up one commutator on each of the failures, as there were 3 wrong corners on one cube and 3 wrong edges on the other.

This is about what I expected - 2/3 accuracy is in line with previous attempts when I pushed my limits a bit. I'm actually very happy with the accuracy considering that I recently switched buffers and am also experimenting with different types of commutators. I definitely did a few comms that I have never tried before.

All in all it was an extremely pleasant hour in the park and I count it as a personal success.

It is absolutely insane, the rate of improvement. Though I'd say a big part is potentially there as your 3bld speed increases so by having ex. a 30s avg, already means that a few weeks of practice can probably get someone to mid 20 or higher cubes from almost no prior multiblind practice. But this of course is not the case, although it probably helped a small amount. Very crazy indeed. 60 is a goal still far away for me, but I might still reach it, if I keep practicing that is.

In my very limited experience, doing more cubes isn't really harder, it just takes longer. By that I mean that my accuracy isn't worse when I do more cubes. Memory palace techniques are pretty easy to use and work very well almost instantly, at least for the volume of information you need to memorize for MBLD. So, I think you are right that fast 3BLD times translate well to MBLD.

Only thing I would see as harder, would be that it gets much more tiring the more cubes you do, actually no. The longer it takes. (which usually means more cubes) So yeah, it doesn't get harder in any other manner than that.
When considering the statements above, please ignore the complete failure I just did: 1/6 cubes. It's like, not statistically significant or something. I was only talking about people who actually have good memo and execution techniques, so my own attempts are excluded.

Among the things that went wrong:

1. Sat outside for this attempt, sun moved, started to feel myself getting a sunburn during the second cube, couldn't move because I had already started solving.
2. A family stopped right in front of my porch to have a very loud political discussion during my execution.
3. Scramble with 4 flipped edges. I was not prepared for this.
4. Scramble with 4 twisted corners. Not prepared for this either. I encounter these so rarely that I have little practice solving them - I will do all of my flips as comms in 3BLD, just to get more practice with this.
5. Forgot to execute parity because my parity memo is not good enough.
6. Many execution mistakes, mostly corner orientation errors.

I could feel the solves going wrong as I was doing them, which is just a terrible feeling. I cheered myself up with some slow 3BLD successes, but even there I made many execution mistakes - thankfully I was able to reverse them, including realizing a mistake 2 commutators later, reversing both, and executing correctly. Quarantine is messing with my sleep, so I will have to try again when I am well rested.

Edit: An hour-long MBLD attempt with 6 cubes is also really pushing my limits - I should not really expect success. I get impatient with my memo and execution, and don't review properly - both because I am feeling impatient and because I need to hurry up to meet the time limits. I will try a few 3 and 4 cube attempts until I can get perfect accuracy, then move up.

Edit 2: I cheered myself up with an untimed 3/3 success. It's difficult for me to get an uninterrupted stretch of time for an official attempt, so I just memorized in pieces during odd moments of free time, then executed very carefully when I had a few minutes to myself. This actually achieves my overall goal of meditative relaxation very well. I did all flips as comms and made sure that my parity memo was extremely vivid, which fixed the problems from my previous attempt.

ResultTime[memo]PointsAvg memo/cubeAvg exec/cubeTotal avg/cubeDateErrorsComment
19/3058:45[40:59]81:21.9635.531:57.513 May 20202 or 3 recall, rest are mostly dumb.first 30 subhour!!
Note: this is PB total/cube, pb2 for exec/cube and a decent memo/cube.
I have mixed emotions about this attempt, since the result is so bad, but then, the time is so good actually. I must admit I had a duplicate scramble, and upon noticing(starting to memo it) I hand scrambled it. I know that in comp, this cube is to be discarded and not counted as an attempted cube, but I really wanted to do a 30 cube attempt today, so I did hand scramble that cube. (From quick search through video, I believe I dnf'd it anyway)

That said, I am glad that I have successfully attempted 30 cubes within 1 hour. Thinking that I would need to halve my time/cube to do 60 seems impossible really haha. But then, if you told me in Jan 2019 that I would be able to solve 15 cubes blindfolded, I would not have been so sure of that. Goal of 42 still stands for the year, but I will need to up my practicing if I want to reach that. I wanted to be able to do 34 subhour by now (as planned in Dec 2019) and as you can see, I am quite a bit far off from that.

I will probably mainly turn my focus to accuracy now, as this is how my top 10 result list looks:
Multi-BLDResultTimePtsDateErrors
PB25/2654:14[35:42]242019/12/29Cube 18: slipped out of my hands and E slice moved. Also I memo'd a wrong sticker so corners would've been off by 2 twists anyway
PB224/2658:58[38:33]222020/03/20C20: skipped over OJ lp in exec. C25:inversed GQ edge comm.
PB320/2149:12[33:28]192019/11/04Cube 7: 3e, might've skipped in exec?
PB419/2052:12[34:03]182019/10/13Cube 18: Memo'd H instead of F for edges. Ironically this cube had only 7 edge letters and I still messed that up haha
PB519/2053:02[34:45]182019/10/10Cube 4: executed BT instead of BE and randomly realised I had done the wrong pair 4 cubes later. Couldn't figure out what I had done wrong (BT) and so just left it. Can't believe that is the only error of 20 cubes.
PB618/1952:12[35:06]172019/10/02Cube 8: stupidly did GX wrong by leaving out the last two moves.. could've been 19/19. this is slow also.. very tired, surprised by accuracy tbh. very not good memo..
PB719/2153:31[35:53]172020/03/11C7: Messed up something during edges, 5e. C16: did PN instead of TN for corners (exec)
PB821/2557:52[40:04]172019/12/17Cube 9: auf error; cube 20: inversed corner PR; cube 23: recalled HL instead of KW; cube 24: missed a two cycle.
PB917/1841:23[27:11]162019/10/28Cube 10: ended cycle too early. Should've done J before the rest of edges. oops
PB1017/1843:33[28:38]162019/09/23Cube4: did DJ edge comm wrong
Pretty 2019ish right?
Worst of all, I mostly attempt 25+ nowadays, and these all rank from 18-26 cube attempts (only 3 are 25 cubes or more)
So I think I will go down and do 17 cube attempts (2 blocks + 3bld) and drill getting fast times (so that I practice the faster, less drilled type memo that is a necessity on big attempts) as well as being very accurate (like 15 solved every time would be considered okay).
And yet again, practice 3bld DYLAN! Many errors occur from my stupid corner twist exec, or those comms that have simultaneous U and D moves (was a common error in today's attempt), so practicing 3bld will help. I am practicing somewhat more frequently, but not enough that I am happy with. anyway, I hope that whoever read to here, was not too bored.
Stay safe, happy cubing!

Don't be discouraged - you are continually pushing yourself so you should expect results like this. If you push time your accuracy will suffer, and vice versa. Congratulations on a new PB time!

28/401:30:56[1:03:04]162020/06/05C1: idc, that whole thing was a mess with memo. C4: recalled the wrong pair, objects too similar. C6: misscramble I think, pretty bad dnf.C9: also. C11: no idea, could be memo.C15: auf somewhere. C17: thought I shoulda flipped UR but was wrong. C19: missed BD flip I think. C22: did GP instead of GN, smol brain.C33: missed an E slice, also recalled out of order. C34: idk C37: something dumb with corners idk man.
Here is a thing. First block went bad, and that caused all reviews involving it to go bad, as well as executing that block. Other than that I was a bit distant during the whole attempt, or I'm just tired. Could definitely have been like 5 -10 mins shorter, but won't focus on this since I need to work on 30 and 33 still. And my accuracy.

Today was a very great attempt indeed. Everything came together nicely, accuracy, and speed across both memorization and execution. Best of all, they ALL achieved better than they have ever done before! (not accuracy, that can't be measured the same but ok)
Today's attempt was meant to be a large mbld (that I haven't subhoured or that I can't subhour consistently) and so I went for 33, as I have subhoured 30 cubes twice (58 and 57 mins respectively). Accuracy was not really the concern here, and it is one of the reasons why this attempt is so insane.

During exec I did feel I was going a bit slower and I felt a lot more confident about my accuracy. I realized this and tried to speed up. (funny enough, this block had 2 DNF's, I don't think it is directly related though) Anyway, here it is:
ResultTime[Memo]PointsAvg memo/cubeAvg exec/cubeAvg total/cubeDateErrorsComment
29/3359:58[41:43]251:15.8433.151:48.9917 June 2020C6: Forgot 2nd edge image. C18: not really sure, Looks like a move somewhere. C23: error while doing NX edges. C28: recalled first two LPs out of order.All PBs. Exec, Memo, Total, and Points. Very crazy having everything not only come together but also be better than they usually are.
I had 1.29 to spare haha, and I'm really glad I did finish before. I'm really happy about that memo/cube. I do think my proportions are a bit out, I feel memo should be faster, but I am feeling a drop in time there. Really great to have a PB memo/cube on this amount of cubes. The avg is also a massive drop. 8 seconds I believe.
Anyway that is all from me, video will hopefully be uploaded in the next few days. 42 is seeming quite possible at this point. Happy cubing, stay safe!

Well, hello again..
uhm.. so.. This is a post I did not think I would be making for quite a long while..
I broke my PB again, and the greatest thing is, it didn't take 7 months! Literally just the following attempt.
ResultTime[memo]PointsAvg memo/cubeAvg exec/cubeAvg total/cubeDateErrorsComment
28/3055:09[39:25]261:18.8331.461:50.2920 June 2020C6: pretty sure I screwed up edge memo a little and did not look at the cube again to notice. C8: did PenGuin instead of Du(Q)cky, when I got to a similar pair a few cubes later I realized I accidentally did PenGuin there but I could not do anything anymore at that point so it is okay.PB exec by 1.69 seconds. Errors are decent, my 3bld practice has helped my exec tremendously.

The 33 cube attempt was arguably better, I do think the memo was quite much better. I was somewhat distracted during the second block. It took over 9 minutes for the full 2 pass (1st block was 8:40 for 2 pass) and 3rd block was a bit rough, I think I was tired so things were a bit slow. Memo did not stick too good but after 3rd review of blocks 1-3 I was comfortable with them all. I was a bit unsure of my memo on cubes 25-29 as they were memo'd quite fast and I was not completely comfortable after 2nd pass but I just decided to go with it. Exec went smoothly on all those. Recall was great.

Happy to see that my errors consisted of 0 exec errors. Only some memo screw-up and recall mistake. With my new speed I am seeing many faults in my pairs like MaP and ATlas. Too similar for me to clearly differentiate between. There are a handful more that need attention and this is going to become a big issue when I reach higher memo speeds; it could already be holding me back.
I do expect a good-high accuracy from this point onwards in multi (for the most part anyway), so the new challenge will be lowering that memo down.
I feel my exec is much better than my memo at this point?

anyway, stay safe, happy cubing!

Quick one, I have to do homework. Tried 36 cubes, worked out as expected. Sub 1:10 and almost 30 solved..
29/361:09:54[48:58]221:21.6134.891:56.523 June 2020C2: messed up LJ. C3: memo'd DW instead of DV. C11: inversed AQ edges. C18:accidentally exec'd corner memo as edges, must've messed up in fixing it. C31: memo error and some where exec nonsense it seems.. C33: inversed VP corners lol. C36: D move.
result, time, pts (if subhour, I actually only solved 15 cubes subhour) memo splits avg, exec, total, date, errors.
Think I will attempt number 30, 33 and 36 from now, goal being to subhour 33 again a couple times until it is consistent and I can hopefully stop doing 30 and then get 36 subhour. Hopefully by end of July, would be really nice. Then I'm almost back on track from my original plan I had at the end of last year. Memo needs to be worked on. First block was very slow today, over 10 min I think. Second block made up for it and was done by 19. 3 pass of 1-3 was done by 35:00 so that is not too bad but I'd like to push for sub 9/block and finish 3rd pass by 30 or less. Exec is not bad, hands were cold today and my mf3rs' are really being difficult with me, will have to fix them up. Not planning on buying new multi cubes out of my own pocket. The extra 3x3s I own should last me to 55 with ease I think.
