Faster works up to a point. That point arrives earlier for unfamiliar material.
| Speed | Time saved on 60 min | Held up? |
|---|
| 1.0x | 0 | baseline |
| 1.25x | 12 min | yes |
| 1.5x | 20 min | yes, for review |
| 1.75x | 26 min | only for known material |
| 2.0x | 30 min | no, for new topics |
Practical
- First pass on new material at 1.0-1.25x.
- Review passes at 1.5-2.0x.
- Drop to 1.0x for worked examples and derivations.
- Captions on helps more than speed does.
