How to estimate it
Fermi’s official “Napkin math”
The easiest place to start is his 24 seasons. He met the big names again and again, but early rounds keep bringing fresh faces. How many new opponents a season? Maybe 15.
- Seasons, 1998 to 2021
- 24
- New opponents a season
- × ~15
- 24 × 15
- ≈ 360
Rounded assumptions may give a slightly different estimate. The official answer above is the game’s reference value.
