Inspection — How to Spend 15 Seconds
WCA A3: 15s cap, 16-17s +2, ≥17s DNF. Elite flow:
- 0-5 s: CN scan, lock best cross color.
- 5-11 s: plan full cross (6-8 moves, ergo-optimal).
- 11-14 s: locate first F2L pair.
- 15 s: confirm grip, start StackMat.
X-cross inspection is the hardest, most rewarding skill. CN cubers see X-cross ~5× more often.
