I guess I should list everything I am learning / want to learn in the future (in no particular order)
- Cross + 1
- Dual CN
- CP prediction during OLL
- Easy LS cases for OLL manipulation / skip
- Easy OLLCPs / 1LLLs
- Full TUL ZBLL
- Easy ZBLS cases to allow me to get a ZBLL more often
- OLL prediction during LS
- Pseudoslotting
If I can do all of that I'll be very fast lol...

How do you test for a stripped screw? My 3x3 seems to (although it might just be me) have loosened itself!
If there's a stripped screw, the faces won't be equal tightness, so I'll find it really hard to set the screws to the same depth when I tighten it later.

Alright, I think I do not have a stripped screw/core, although while testing screw depth on all sides, I found out that I had set red/orange to 45 degrees too loose, not much of a difference but it is a little noticable.

Also mgc 4x4 + many drops of martian = god tier, I got a PB single with no luck (apart from no parity), even though I barely ever do 4x4:

a minefield
Believe it or not, RUS Ub is even cooler than RUS Ua, and can be done from homegrip.
I'm considering using it in solves just like Ua to become certified swag.
(R2' U R2 S R2' S' U' R2)
imo not as good as Ua on fingertricks though
I came up with a Ub alg, it's basically two RUS Ua with cancellations, but I think it has better fingertricks. (more moves though)
R2 U' S' U2' S U2 S' U2 S U' R2 (follow the U2 and U2' for the good fingertrick)

I think the Ub fingertricks are as good, but a lot harder:
/Home grip/ R2' U (w/ left index) R2 S (w/ right index) R2' S' (w/ left index) U' (w/ right ring finger) R2

There are no overworks or regrips, it's just a bit fiddly (?)

There's definitely reason to use both:
Movecount
Ub - 12 QSTM, 8 STM
Ua x2 - 16 QSTM, 11 STM

Other
- Ua x2 is much easier
- But Ua x2 requires a small regrip

I'm gonna stick with the shorter alg, I just have to practice the alg constantly (it took me over an hour to get Ua alone up to speed)

Decided to practice the RUS U perms on cstimer, here are my PBs after about 45 mins of straight grinding:

RUS Ua: 0.43 (7/0.43= 16.27 TPS)
RUS Ub: 0.65 (8/0.68=12.30 TPS)

Bear in mind these are not framecounted, because I can't be bothered to do that, but these would probably be faster if I framecounted them.

Edit: RUS Ub: 0.58 (8/0.58= 13.79 TPS)
Edit edit: RUS Ub: 0.54 (8/0.54= 14.81 TPS)
Again: RUS Ub: 0.53 (8/0.53= 15.09 TPS)

Idk what framecounted WB is for these but if I'm close enough I might go for them.
