Blindsolving Discussion and Help

Assuming you are using m2 to solve edges on a 3x3, and out of all the edges on the L and R faces only 1 edges is correctly placed yet flipped, and assuming FU, UF, UB, BU, BD, and DB are all solved with individual algorithms, will the the buffer piece always be flipped but in its correct location at the end of solving the edges?

If all the other edges are in place, the buffer is in place. Of you have an odd number of flipped edges excluding he buffer, the buffer is flipped.

Thank you. That was what I was assuming, just double checking that I wasn't being stupid/overlooking something due to parity since I have not used M2 for a while.

the only way that i know is like (R L') F2 (L R') U (R L') F2' (L R') U' (comm notation: [[RL':F2],U]) which for a 3x3 would be something like M D' M' U M D M' U' ([MD'M',U])

This is exactly what I use for megaminx edges BLD. It takes forever; I orient-permute, and (orienting all edges + orienting all corners + solving all corners) takes approximately the same amount of time as permuting all edges alone. I wish there were a better way to permute edges on megaminx, but I haven't found one.

To people that do 4BLD and 5BLD a lot : is your success rate pretty high? And i mean like, it's rare that I dnf 3BLD now, does it ever get that consistent with big cube bld?

I still DNF a lot! I think the %'s are as follows for me: 3BLD - 70%, 4BLD and 5BLD - 30%

Interesting. I want to be able to say "i can solve a 4x4 blindfolded" with the same confidence as when i say 3x3 blindfolded. When i do 3BLD, i KNOW it will be solved, but on 4x4 i'm still a bit sketchy, but i'm getting atleast 1 success a day, today i've gotten 2 though.

I'd love to be that accurate with big cubes too, since for me 5BLD successes are somewhat therapeutic but having to sit through 3/4 DNFs before you get one isn't exactly worth it (not a huge fan of doing safety solves either.) If I have time I may sit down one day, work out everything I do wrong and work on accuracy/fast safety solves.

 

[HEART]

Which is wierd coming from you, with that 3 minute 4bld and 8 minute 5BLD, it would really bother me if i got that fast at them but wasn't as consistent, i honestly want a balance of speed and consistency.

I have never really had high success rates at big cubes BLD (except for very short phases). I did consider myself to be relatively accurate at 5x5 BLD around mid-late 2011 (maybe 50-75%, however, my competition results suggested otherwise XD).

Chris has extraordinary big cubes BLD accuracy, I remembering him once getting a 5BLD average of 12! (and fast times too). Marcell also has some impressive accuracy.

 

[Marcell]

To be fair, I myself never got to the point where I could safely say that 'I can solve a 5x5 blindfolded'. Not even 4x4.
I can be relatively accurate, but something like a 3x3 safety solve with 99% certainty just doesn't exist for me on bigger cubes. My two main risk factors are doing a wrong center comm and missing a short cycle on wings.

 

[DrKorbin]

and missing a short cycle on wings.

So you don't count how many wings you remembered and how many cycles do you have?

BTW, the main reason of my instability in big cubes memorization is memorization of wings. If there is one or two big chains, very good. If there are 2- or 3-cycles, I can search them for ages. Is there any good way to track wings you have not memorized?

 

[Marcell]

So you don't count how many wings you remembered and how many cycles do you have?

Ain't nobody got time for that. Only on safety solves.
Normally I can tell that I'm done with them. Except for scrambles with lots of short cycles.

And as far as I know, an efficient way of telling which wings you haven't memorized yet has long been missed.

so I've been practicing bld for about a year and a half now and I'm about sub-2 with M2 and OP.

I've started mixing in bh for corners but should I use turbo edges?

If you're used to M2, turbo won't really speed you up. It's good to know turbo though and use the algs sometimes when they come up.

Where to get a blindfold?

I avg 5:30 with old pochmann. Memo is about 2:30. Should I switch to m2 for edges or keep pushing myself with pochmann.

You can get a blindfold at almost any cube shop, cubedepot has one.

Try to push your memo, your memo should be at least sub-2.

If your not doing it already, you should at least start using some J perms instead of some of the T perms. Shooting to FD have (l') or (M') as setup move if you use J perm, while (D' L' d' L) is needed if you use T perm. UF and UB have 0 setup moves (you might have to do some AUF, depending on how your J perm algs are).

M2 is a bit harder to grasp, but when you do, it's (imo) easier than Old Pochman.

I'm not the best at explaining stuff, but I hope this is to some help.

This may or may not be helpfull for you, but I got a bunch of blindfolds from a retired pilot's garage sale. Blindfolds are in almost every airline's gift bags. So I guess you could ask some friends if they have any around the house. If you do it this way, you may end up with enough to pick your favorite blindfold and still have spares (for free).

The only problem is that once you get good, DNFs are usually due to doing just one small thing wrong. If you do one thing wrong out of every 10 3x3x3s, with 20 pieces or so to solve per cube, figure that you have 50 pieces to solve on a 4x4x4, so if you make mistakes with the same rate, you'll probably wind up averaging about 2 1/2 things wrong per 10 4x4x4s. So if you have the same accuracy piece-by-piece with 3x3x3 as with 4x4x4, and you average 90% accuracy on 3x3x3, you're liable to be no better than 80% accuracy on 4x4x4, and even less than that on 5x5x5. At home, I average pretty close to 85% on 3x3x3, and I haven't kept statistics, but I'd guess I'm around 66% on 4x4x4 and 50% on 5x5x5. It seems to me that's probably very similar accuracy on all three puzzles on a piece-by-piece basis, so I'm pretty happy with it. Unfortunately, by the time you get up to 7x7x7, the accuracy naturally gets fairly low, but I probably hit around 30% of them.
