01PLL recognition is about piece cycles
Bars, headlights, opposite colors and adjacent blocks reveal which corners and edges must move. Two-sided recognition uses the front and one side to identify the case without a full cube rotation.
The complete skill includes selecting the case, aligning it with AUF, starting from a known grip and finishing in a predictable position. Fast turns cannot recover time lost to a recognition spin.
02A practice sequence that builds the skill
Learn T and Jb as friendly RUF algorithms, then U perms for edge cycles, H and Z for slice patterns and A perms for corner cycles. Add similar G, N and R cases only when their distinguishing cues are stable.
Create cases with setup moves, present them from random U rotations and require identification before execution. Time recognition and execution separately, then practice PLL plus final AUF as one finish.
03How to measure improvement
Track average execution per case, best time, accuracy and recognition delay. A SupaKewber algorithm page can show community execution averages once enough user attempts exist.
If a case has a fast best but a slow average, the grip or recognition is inconsistent. If both are slow, test the alternative algorithm and study finger-trick transitions.
04Common mistakes and what to learn next
Avoid learning mirror cases as one vague picture, starting with a regrip or stopping mentally before AUF. Slice algorithms require deliberate M-move finger tricks rather than whole-hand turns.
Begin with T-perm, Jb-perm and Ua-perm pages, then expand through the PLL hub in recommended learning order.
