Training Methodology — Quantitative Practice
Cumulative solves vs PB threshold (community consensus):
| PB | Cumulative | Calendar time | Daily |
|---|---|---|---|
| Sub-30 | ~1,000 | 1-3 months | ~50 |
| Sub-20 | ~5,000 | 6-12 months | ~50-100 |
| Sub-15 | ~15,000 | 1-2 years | ~100-200 |
| Sub-10 | ~50,000 | 2-4 years | ~200-300 |
| Sub-7 | ~150,000 | 4-7 years | ~300-500 |
| Sub-5 | ~400,000+ | 6-10 years | ~500-1000+ |
| Sub-4 | ~10⁶+ | talent-bound | — |
| Sub-3 | ~10-person club | — | — |
Practice composition (consensus):
- ~60% csTimer-timed solves
- ~15% slow / forced-lookahead solves
- ~15% algorithm drilling (case-frequency-weighted)
- ~10% review (video / smart cube)
Training-comp gap: 5-10%. Causes: cube cooldown, scramble verification delay, anxiety, no warmup.
