Blindsolving Discussion and Help

[antoineccantin]

How much do you review? I would suggest slowing down a bit so you don't need to review as much which will actually make your memo faster. Based upon your tps in other solves, execution is probably already very good for you.

EDIT: Also, if you are using the same rooms/journey's too often, then they tend to get less vivid/slow for me with overuse. You can either give them a break for a couple days or make new routes.

Many thanks to you kind sir. I just did an attempt applying your advice and got 8:20.20 PB first sub-NR

That's great to hear and a good start! It takes a lot of tweaking to find out what works best for yourself. And congratulations on your first sub-NR for 4BLD!

Have you ever been to a competition at all?

I was at one last January and DNFed everything. I plan to go to the competitions in my area this fall.

I don't use a DF buffer so take this with a grain of salt. do you like [L2: D',M'U'M] and you can do the L2 M at the end as (l L)

This one's nice! Ta

I review quite a bit. I also always use the same room for 4BLD, so that is probably part of the problem as well.

I generally use just 3 rooms for 4BLD, so I reuse a room every third solve. I find that is plenty enough to pretty much eliminate problems with reuse; I can go all day without decreasing speed or accuracy. So maybe you could just create two more rooms.

How do you orient corners when they aren't oriented correctly?

you could treat each twisted corner as a cycle and do something like
R2 Yperm R2
D' F' Yperm F D

but I just do setup moves/commutators

Has anyone attempted or solved the curvy copter blindfolded?

I have a method for how I would approach it if I knew beforehand that the puzzle had not been scrambled with any shape changing turns. I'm still not sure how I would approach it if the puzzle was given to me in cube shape, but I knew that it may have been scrambled using shape changing turns.

How to 4bld? Mainly centers. I'm fine wings and corners. Should I do u2 or comms?

I thought about curvy copter and found it relatively easy to solve if all edges were rotated by 180° though didn't find what to do if not.

As a beginner, use U2. Try to do comms with open eyes. When you feel fine with them, use them for normal bld.

Start by comms , if you find it hard , switch to U2 , it's fairly easy
I'd recommend dan Sheppard's 4BLD centers tutorial

 

[ilikecubing]

fast algs for ULB-BRU-URF and ULB-URF-BRU?

 

[tseitsei]

ULB-BRU-URF: R'[L' D2 L: U2]R
ULB-URF-BRU: inverse of the above... R'[U2: L' D2 L]R

That's what I use atleast

Ok. Thanks. I'll try that.

Am I allowed to use different sized cubes in multi-blind?? (in comps)

Yep.

 

[TheNextFeliks]

For 4bld centers:

A. What buffer should I use?
B. Should I use a floating buffer or what should I do when buffer is filled?

 

[DuffyEdge]

Yep.

Nice, thanks

Are you using U2 for centers?

 

[TheNextFeliks]

Wanting to try comms.

A pretty good question, actually.

A. I use Ubl, which is good if you like doing r-slice moves. Oleg uses Urb and is good with l-slice moves (unlike me) and is bloody fast.

B. I think Marcell and Oleg both use fixed buffers, though it is more than possible to sub-6 5BLD and sub-3 for 4BLD without it (because I still use floating buffer, and I'm getting faster...) but I'm trying to move on to a fixed buffer.

The advantages being:

1. You can learn an alg for each center comm case and rehearse it until it becomes automatic (removing thought, which would be an issue with a floating buffer.)
2. You can avoid having L2C by breaking into odd cycles with your fixed buffer.

However, I have learnt a lot of special cases for other buffers, so I can set-up to fast cases for other buffers with no thought whatsoever. So in theory, you could learn a lot of algs for all center buffers and save moves and therefore save time in execution (but it's a ridiculous amount of algs.)

Stick with floating buffers for now. But for advanced big cube BLD/in the very long term, go for fixed buffer. It's a lot to learn, but worth it.
