Largest number of cubes possible in old-style multi attempt

[Deleted member 36445]

Yeah I've got first person evidence for that too. I regularly do 24-hour fasts and it's not that hard to control hunger for a day imo.

yeah you just have to eat

Graham is going to do a 250 cube MBLD attempt soon.

I am hyped about it. Estimated attempt time will be 5-6 hours. Super stressful as we increase the number of cubes.

Yucheng Chen and Tom also do old style attempts at home sometimes but they are nowhere close to 250 cubes.

I know Maskow did a 150 cube attempt about 7 years ago. And I know Graham has topped that since then. But has anyone else besides Graham done over 150 cubes before?

Edit: I guess you said earlier that Yucheng Chen and Tom have both done 150+ cubes. How big were their biggest attempts so far?

Hey Mike.

Tom tried 200 *twice*, a couple of years ago, actually before I even tried 160. His best result out of the two was 162/200 in over 12 hours.

As far as I know, Yucheng's biggest attempt was 100. He tried it twice, first getting this, and then this.

Shivam has also tried 100, getting 87/100 just like Yucheng.

So as of right now, I've done the biggest ever attempt by 50 cubes. I also have the top 3 best points results at 154/160, 189/200, and 238/250. Tom has the fourth best points result with 162/200, and Maskow has the fifth best result with his 125/150.

Waiting for Graham's 300 cube attempt at the year end. It will be epic!

I think that we may have forgotten, due to amazing feats by people like Graham, that even the best people slow down as the numbers go way up. I really doubt Graham could do 2000 cubes in as little as 5 days. I think it might take him as much as 2 weeks. And with the old-style rules, you'd have slightly less than 2 weeks to do an attempt (10 minutes per cube time limit).

I have had some time to give to this topic and have started to believe that 2000 is actually possible.
I think a person who can do 50 cube multis sub-hour comfortably should be the one trying this. (There are 10+ people capable of it as of 2023)

There are a lot of factors which can dampen or taper off the upper limit of 2000:

1. Memory capacity: Assuming we have 2000+ rooms ready, there is still a capacity to our retention
2. Time and human body essentials: Given the brain intensive task, sleeping more than 12 hours will be a good idea. Also doing a review of the packs of yesterday will be necessary as 5 pass memo does not guarantee retentivity over 12 hours of sleep
3. Concentration: Unless the person is a saint, there will be some things to tend to on a daily basis, which will distract the person. Even if they do not do the task and just focus on memoing
4. Motivation: This task is energy intensive. Even if there is monetary benefits and cheering up from the speedcubing community, advising the body to undergo this will be hard. Ultra-Marathon runs will help as body requires similar mentality there.
5. Confusing review systems: Keep track of the review system will be more of a pain than retaining the memo, once the memo is complete then the confusion no longer exists. But the memo period will be hard to do, as we have to jump between new information periods and review of old information periods.
6. Cube arrangement too large: Arranging 2000 cubes on multiple tables will be a big task. A few helpers will be needed to navigate between tables. The helper should be allowed to say that this table has these cube numbers.

all blind is wizard magic so i think infinite since your already using magic why not use a bit more

If we’re going complete physical limit (not biological limits, but physics itself) then this is my guess:

so let’s assume 1 solve takes up 1gb of storage space, and assuming you know nothing else but mbld, and you were given eternity, the physical (not biological) would be 2.5 million cubes (the brain has 2.5 petabytes of storage space)

How long would this take?

let’s assume a top BLD silver can average 15 seconds per cube, that gives us around 434 days of straight MBLD. (not accounting for scrambling time) And while we’re slapping all these, admittedly Insane assumptions, let’s assume our little test dummy never messes up, doesn’t need to sleep, eat or drink, and doesn’t succumb to fatigue.

This mass of cubes would be over 7.6 square kilometers.

Those scramblers better start scrambling

7.6 km^2 of cubes is just not feasible.

A better way to go about 2000+ cubes old style attempt, is to use a smart cube, and print the next scramble on its face, so that the competitor does not have to move.

If the competitor wants to do reviews, he can give voice commands to the smart cube and the scramble of cube number X will be colored out on the cube.

I imagine this to be convenient and practice when old-style multi gets 2000+ cubes. I take the number 2000 as it is roughly the number of cubes we can fit in a closed big room.

Insane attempt 288/300!

And with the old-style rules, you'd have slightly less than 2 weeks to do an attempt (10 minutes per cube time limit).

I think the maximum is probably somewhere over 500 but less than 2000, assuming the person is allowed to take whatever breaks are necessary for eating and sleeping, but the 10 minutes per cube overall calendar time is enforced.

I don't think enough rooms is a problem. Generating lots of new rooms to use can be done very fast, especially if you're motivated by trying something this major.

I think it's sad, but my personal limit at my best was probably around 60, because of the time limit and because I was so slow. :-(

Rough details of the attempt (subject to change after discussion and feedback from you guys):

1. This is my take on how I will plan my attempt. I am no where prepared to pull this off in the near future, but it is good to have a plan to start with.
2. I know the 50 cubes at once MR is not popular and may not go well with many MBLDers. But I want to stick with this spaced repetition scheme for this attempt. I am assuming 3:30 MR for each 10 pack.
3. The execution order would be to do 1900-2000 cubes first, and then move onto cube 1.
4. Sighted walking between tables should be allowed.
5. Assuming 100 cubes can be kept on 1 table, a total of 20 tables would be needed, the setup would look like a chess simul hall.
6. I currently have only 350 cubes and have made 450 rooms in my Anki deck, there is still a lot of work before I become even ready for the attempt. I also need to buy 16 more tables as I have 4 folding tables at my house.
7. Streaming this attempt will be whole another ball game, I think 2-3 full time cameramen need to be hired for 5 days.
8. Nutrition during memo will be crucial so a lot of brain food, and nuts should be consumed.
9. A bit of exercise between stretches of memo would be ideal, keeping a gym cycle in the center of the room would be ideal, similar to how Timur Gareyaev does his chess BLD simul attempts.
10. The execution would take around 11-11.5 hours assuming 20 seconds per cube exec speed, so I am counting the entirety of day 5 for execution.

I’m not familiar with MBLD terminology. Does 5th pass mean you go back and make sure you’re memo is right for the 5th time?

 

[abunickabhi]

I’m not familiar with MBLD terminology. Does 5th pass mean you go back and make sure you’re memo is right for the 5th time?

Rather than make sure, we try to reinforce the memo into the long term part of our brain, by using spaced repetition.

 

[abunickabhi]

With Graham doing 350 cubes in 12.5 hours, it redefines what the limit is.

I feel per day limit of 500 cubes memo seems so much possible now.
