1x1 wr holder's Progression thread | sleepy college guy

[1x1 wr holder!]

You spelled new as knew in your progression thread title.

thx, I changed it.

 

[randomness...]

thx, I changed it.

its gnew now, not sure if its intentionall

 

[1x1 wr holder!]

oof, having trouble with 4x4. maybe it's cuz the lube hasn't broken in yet, but I'm falling out of the sub-1 range. getting lots of 1:01's. perhaps a 1 day break is in order.

And guess who forgot to bring their oll sheets on vacation… oh well, I guess I have my phone.

You could download the cubeskills one as a PDF iirc

I’m doing okay on my phone rn. Just learned two more algs

I new it but who old *you* that? ¯⁠\⁠(⁠°⁠_⁠o⁠)⁠/⁠¯

Okay, 4x4 break is over lol. The lube just broke in and I got a 48.219

You should learn OPA. No more parity lol

Wait, what’s OPA? Sounds too good to be true

Oll parity avoidance. Basically, you scan a wing to it's corresponding partner and see whether it's good or bad, and from just scanning the wings you can determine the cube is in an even or odd state (which means the cube has had an even/odd number of slices done on it). Then, as you solve, you keep track of the # of slices you do, so once you get done with your first center (assuming you use Yau) you won't have parity once you get to 3x3 LL.
The idea of no parity is kinda misleading I'd admit. You'll still get pll parity sometimes but you won't get OLL parity, if you do it right. Check out my thread about the rant @LBr did on it.
It kinda follows a 3bld approach where you see where edges will go, but in this case it's where wings will go corresponding to their mates.

Oh so like in 3bld when there is an odd amount of edge swaps, you do an r perm. Thx, I’ll look into this

Well no. You "fix" Oll parity just by doing the solve as normal, but you keep in mind the number of moves that you do relative to whether you determined the cube is in an even/odd state. So like if I determined a scrambled 4x4 was odd, I want to make sure that by the time I finish the first center the cube is in an Even state. And if the cube was even I'd want Even as well, since Even means no OLL parity.

Stanley Chapel has a good video on it

He also links to another video that more thoroughly covers the mechanics of OPA

side note: Sebastian Weyer (4×4 WR2 atm) stopped using OPA about a year ago...
so I reckon: being realy good + fast is good&fast enough

haha good one there mang
I mean oops, that's the same video Scalpel links below his OPA vid

 

[1x1 wr holder!]

Okay, I’m learning OPA. I know how to count cycles and I’m comfortable with counting the slice moves up until my third center. It seems worth it and is pretty cool that something like this exists. Thx @Garf

 

[artless1der]

I think I remember CubeMaster had a video about avoiding parity on even cubes...
but it wasn't OPA per se
iirc his deal was to use trigger moves throughout building centers
that way your slice move count stays even

Plz no opa , OP is fun.

 

[Arcanist]

As @LBr has mentioned, you probably don't need to learn OPA yet.

I've never seen a statement that I agree with yet full-heartedly disagree with.

As @LBr has mentioned, you probably don't need to learn OPA yet.

I agree with this

There's not really a need to learn OPA. If you can execute the alg in around 5-8 seconds, you should be fine to keep doing it when you get parity. What I would say is learn OPA when you get to sub-30. Only by then should it really matter.
