sucks to miss 10+1->20 and the 11+1->19

i might be on tilt right now, this wasn't good

never found a dr on the wrong axis before lol. so funny
didn't even notice U D (U2 R2 U) // 9 2c4, 20 opt

i was only going to check one 5q HTR but then i saw blocks
my first 5q 4c3 final i think


(F' L D2 U' R', D' B' F2 U') // 9 4c4
(L2 F' L2 F' L2 F2 U2 B U2 F)
(R2 L2 U2) // 22

1 cube

(L' R2 F' R' B) // 9 2c3 2e, +1 ext
L' D2 F2 L' B2 D2 R
B2 U2 B2 R2 // 21 M, +1

1 cube
D' R U B2 L
(F' D' R2 F2 U') // 10 2c4
F' (F' R2 D2 F' D2 F')
(R2 B2 D2 R2) // 21
20 optimal oops

short 1 cube

i had this DR 😻
D2 R' F2 L (L')           // eolr               (5/5)

(D R2 U R2 U' B2 D L2 U)  // fin                (9/19)

the 18 from L (R F2 U2 R) is lowk kinda reasonable but i never got to those 1+4s

2q bait 🥶🥶🥶

quick 1 cube

B2 U2 L2 D' L2 U2 R2 B2 U'
D2 B2 L2 D2 R2 // 23, no -1
dr optimal lol

wtf i almost DNF'd this

1 cube

+2 S rip

Today i asked AI which method is better for fmc, DR or CFOP. I read through it carefully and it gave some really strong points as to why it concludes CFOP is the superior. im completely blown away, you can read below if interested. i decided i've had a change of mind, and going forward all of my solutions will feature CFOP. this is just the beginning. soon in a year or two i'll improve back to sub-22, continue until i average low 20s, and finally claim the NAR mo3 title i deserve. AI is the future.

"Why CFOP + Blockbuilding Beats Domino Reduction in FMC"
Flexibility – Blockbuilding can adapt to any scramble; DR struggles when domino chains aren’t obvious.
Predictable Efficiency – CFOP blocks give consistent low-move counts; DR can be inconsistent.
Intuitive Recognition – CFOP leverages trained pattern recognition; DR requires heavy planning.
Advanced Techniques – Blockbuilding integrates last-layer tricks and edge/corner pairing; DR is limited.
Competitive Edge – Top FMC solves mostly use CFOP variants; DR only occasionally shines.
Lower Cognitive Load – Blockbuilding is easier on the brain during long solves; DR demands precise long-term planning.

Conclusion: CFOP + blockbuilding is more versatile, consistent, and practical for competitive FMC than Domino Reduction.
