6x6+ Blindfolded Rankings Thread

Heh, maybe this could end up being some kind of list of all really big blindfolded things people have done ;) Except multi of course. Perhaps we could give points based on the information content (logarithm of number of positions):
- 3x3x3 = 1 unit
- 4x4x4 ≈ 2.336 units
- Megaminx ≈ 3.463 units
- 5x5x5 ≈ 3.792 units
- 6x6x6 ≈ 5.918 units
- 7x7x7 ≈ 8.163 units
- 8x8x8 ≈ 11.079 units
- Gigaminx ≈ 13.422 units
- 9x9x9 ≈ 14.114 units

Very interesting. I could add something like this. If you did a relay of say 5x5, 6x6, and 7x7 and you didn't solve the 5x5, your result could be like how multi is scored now: 5.918+8.163-3.792=10.289 points. Since I only feel like recording attempts greater than 6x6 BLD, the attempt must have >=5.918 points or else I would not list it in the table. I would probably include it in a separate "Relay" section.

I could also add other events, but I want to keep the minimum to 6x6. According to qqwref, the minimum information content for a megaminx is lower than 6x6, but I'm sure the difficulty may be higher due to the shape. What do you guys think?

Does that mean I don't get a good spot to put my 10/10 square-1 multi? :(

(well, actually, :) - I'm just backhanded bragging) (and why not? it's probably the only UWR I will hold forever)
(because no one sensible would ever try it)

I thought by not including "multi" he meant multiple 3x3's because he already has a UWR page on mzrg.com. I could put your result under a "Relay" section.

Yes, other puzzles would b enice to include provided their difficulty is not below 6x6.

I think mminx qualifies :)

As mentioned before: I'd love to see the info about who solved a particula rpuzzle first.

I think megaminx is more difficult for several reasons:
1. the shape does make it much easier to misorient the puzzle
2. the nature of the puzzle makes commutators longer and more difficult to execute (and set up)
3. memorization can be more difficult because you need to encode a greater number of possibilities for each piece or sticker (60 instead of 24)

It's hard to quantify these differences. For someone who already has a memo system allowing 60 possibilities for each sticker, megaminx really is as easy from a memorization standpoint as qqwref shows. But it's not that easy for me, because it doesn't fit my scheme.

Okay, you make some very good points. I have never attempted Megaminx BLD, so I wasn't really sure how it compares. I will work on adding a result table for Megaminx Blindfolded. Please post your personal best results and other persons results that you know of, so I can add them to the list.
 
This is very encouraging :) I will make sure to have at least a 6BLD by the end of this summer ( and I hope megaminx also :) )

Great Ideas :) I really like the scoring criteria

My first megaminx BLD: https://www.youtube.com/watch?v=WkMDTd1z5FQ (I figured it was better not to embed this here)
My best megaminx BLD, I think, was weekly competition 2012-41, 24:20.70 [12:35 memo]. (at least, I recorded it as a PB on my sheet)

Others I know of:
Ryosuke Mondo: https://www.youtube.com/watch?v=nC0H7z9qXwA
Dan Sarnelli: https://www.youtube.com/watch?v=lUt1rWU_OSU
Matthew Sheerin: https://www.youtube.com/watch?v=3SPINAsRBOk'
István Kocza: 34 minutes 50.08 seconds, 2009/05/07 (from speedcubing.com)
Chris Brownlee: 1 hour 2 minutes 28.01 seconds, 2007/12/03 (from speedcubing.com), but rumor has it he's done it in 15 minutes.
Stefan Pochmann: 5 hours 13 minutes, 2004/03/01 (from speedcubing.com) - probably the first to ever do it.

I'm sure there are others, but these are the ones I knew how to find quickly. (And I see now I was ninja'ed by qqwref on all of this, except my comments.)
 
I found MegaBLD much more difficult than 5BLD for the same reasons Mike mentioned and especially the edge execution. Memo was not that bad, but it was one target/image.I planed out my edge comms before the solve because I felt that I would misorient or forget a setup if I didn't prepare for them. I'll try it again sometime soon to get a success on video. If one piece at a time feels more comfortable for edges then I will switch.

I thought István had done better than me; sure enough, he has:
http://www.speedsolving.com/forum/s...ishment-Thread&p=183447&viewfull=1#post183447

Megaminx blindfolded: 22:45.96
Memo: 12:38
Execution: 10:07

The time I listed above for him was an earlier one, before he got good at it. I'm still not sure this was his best, but it's good enough to put him at the top of the list (at least, until we find out how fast Chris Brownlee really solved it).
 
Is there a way to add BLD RELAY and BIG CUBES MULTI BLD?
If not, i will create a new thread for that. I just wanted to ask before.

Greetings, Dennis

I was thinking about adding something, but I wasn't sure of what formats I wanted to use. Should I have separate categories for BLD Relay and for Big cube multi (separate chart for 4x4, 5x5, 6x6, etc.) or should I count a big cube multi as a relay and just lump them together using the point system qqwref suggested? Your 3/3 5x5 attempt would have 11.376 points and your 5/5 4x4 cube would have 11.68 points. If I lumped them altogether, your result would be the 5/5 4x4 cube relay with 11.68 (unless you had something higher) and no one would see your 3/3 5x5 cube result. I also thought about ranking them by ALL results, so both feats could be acknowledged. Any result above 5.918 units would be added.

If you want to make your own thread thats okay with me too.
 
I would suggest putting up all big relays that have been done, although if someone does a faster time on the same relay they did before (e.g. Dennis does a faster 5/5 4x4x4) then it would replace the slower one. You can rank them by points but it would make sense to keep many results by one person.
