View attachment 8783 Sooooo... this was my first attempt at a full (corners and edges) blind solve. Bear in mind I started Friday or Saturday.... I’m pretty sure I had my memo right, but question:

Is this the “parity”? And how would I have know? The E and Q edge stickers are flipped and the opposite corners (c-j-m) and (b-q-n) are swapped.

OP/OP? Not QUITE. If it was, it'd be an R perm, and your corners would be oriented.

General questions for parity:

Did you have an odd number of corner targets?

Did you have an odd number of edge targets?

If the answer to both is yes.. you have parity.

If the answer to no is both, you don't.

If the answer to both questions is different... you have a problem.

 

[SpartanSailor]

OP/OP.... yes

I think I’m my memo I failed to recognise the two corners. I memo’d them as “flip but remain in place” and I think I miss identified them. Meaning, I should have moved them during rather than flip them.

I may have had a parity, but I’m not sure. I thought I had 4 corners to solve and 3 corners to flip. Is that even (4 to move) or odd (4 plus 3)? That’s the piece I’m still unclear about.

All said, I was still pretty stoked to get that close. Lol

I am a rookie at blind, so I don't memorize "twists" usually. But if a corner is twisted, you can always count it as a cycle of two targets. (Target a sticker on the cubie, then target where that sticker should go, and that will twist the corner.)

But your W/R/G and W/R/B corners are in the wrong spots... so you missed part of memo is my guess, also is it me, or do you have two R/W edges? (Those colors are rough on my eyes.)

 

[SpartanSailor]

The one on the blue face is orange... the lighting makes those difficult to distinguish on the picture.

I’m betting I forgot part of the memo too... first attempt, shouldn’t expect to nail it ‍

 

[phreaker]

What is your orientation? Which face is F and which is U?

 

[SpartanSailor]

F is green. U is white. That picture was NOT my orientation. Just showed most of the errors.

My OP edges buffer is UR Center, White-Red edge.

 

[phreaker]

Your finger is over the White/Blue edge? If so, you didn't have parity, and forgot a cycle.

 

[SpartanSailor]

Yep. My finger is over white-Blue. Yeah... well, I gave it a shot.

I just realised the parity is the R-Perm I use if I do a U’ before the alg then a U2 at the end. Does it still work out if I do that between edges and corners? Can I do it at the end of everything? Or does it have to be “edges-Parity alg-corners” in that order?

 

[SpartanSailor]

Btw... thanks. I appreciate your time and assistance. This would be SO much easier if I had anyone to actually talk to about this!

 

[phreaker]

R perm is the parity for OP/OP last I knew. Note, I solve with M2/OP, so my parity alg is different. M2 is pretty easy if you know OP corners. The only hard parts are the center slice which takes some practice.

Honestly, I'm just doing corners only practice tonight while I work on overhauling my memo system, . (Shifting from PAO -> 2 letters per word..)

 

[SpartanSailor]

R-perm works hen I do the U’ to start and U2 at the end.

I tried another and as luck would have it, there WAS a parity. So, I did it sighted to see if the parity alg worked... and it did. Now, I just gotta get that memo down!! Lol

I know OP edges is less efficient, but for now, I’m just trying to get the basics down. I’m sure it won’t be long before I look into M2.

Thanks again, and good luck with that memo practice!

Thanks! OP edges would have been real rough for me. I only know OH PLLs , and I certainly don't know them 2H so well I can do them blindfolded . I even had to learn the truncated Y perm for OP corners... My OH Y perm is very different.

I've thought about learning OP/OP to do OH BLD at some point... but that's a ways off

OP/OP uses T-Perm, mod-y-perm and now, I realise, R-perm. So, those don’t require any thought from me... that way I can focus all my brain power (what limited I have) to the story I need for memo. And apparently, that’s still coming up short. I’ll get it. I just want it to be on film when it happens! Lol

 

[openseas]

@SpartanSailor / Number of targets are:

- corner: 7 + No of cycle breaks - number of solved or twisted pieces
- edge: 11 + No of cycle breaks - number of solved or flipped pieces

as @phreaker wrote, you should have both even or both odd numbers. You need R-perm parity (for OP/OP) when you have both odd number of targets.

BTW, once you are familiar with memo, recommend to learn M2 for edges instead of OP. Much advanced and faster.

Welcome @SpartanSailor, I like Chris do not think I ever said hi yet. I was also out of town for about a week and a half and just returned today. I got quite a bit of practice in over the break relative to what I have lately, I'm getting close to 1:15 average in 4x4 finally.

It sounds like you are doing similar to what I did with starting blind. I learned op/op and spent probably about a week or two on that before going to M2. The biggest advantage for me was being able to do an entire sighted solve and watch what happens, especially when I was getting confused with cycle breaks. I had just a few successes and then switched to M2. Good luck!

Happy New Year to all as well!

@SpartanSailor: close one... you'll get it, won't be long. It can be good to keep track of your scramble so you can go back through later and figure out what went wrong. After learning the mechanics, I had about 2 days' worth of fails on full attempts, including several "close but no cigar", until I finally got the first one. Keep attacking it.

I keep the scrambles handy until I'm done. I started filming myself too (just with my phone) so I can watch the execution too. I don't write down my memo every time, though. I'm trying to keep it in my head. But, as long as the scramble is there, I can recreate my solution by looking. When I drop part of the memo, it's pretty clear as I trace through the second time.

One thing I have noticed is that the time just gets away from me. I sat down around 7p last night to practice and next thing I knew it was 9:30p. I guess I just loose track of time during the memorizing.

My phone is my only camera.

An hour and a half has always slipped by me no matter what cubing I'm practicing.

Check it out, I won!

Gentlemen, Happy New Year to all of you and enjoyable cubing in 2018.

I would also advise you to go straight for M2 edges. You will have to deal with switching M2 centers, but once you get it , everything is more logical. When I started, I tried both OP edges and M2 and after a few days, I went straight for M2. Also, I prefered the parity alg for "edges first-corners second". D' L2 D M2 D' L2 D. Yes, you need to memorize two nasty FU and BD algs. Once you get into M2 you can learn how to avoid them, thanks to Mark's advanced M2 instructions, but that later. https://www.speedsolving.com/forum/threads/advanced-m2-guide.56076/

Best attempt yet at 4BLD. Only had 15 mins left of my lunch so I rushed it. There's small errors on each piece type. I think centres are an execution error. Corners must be memo error and not sure about wings.
