How we compute these metrics
- Grade rates: averaged across cards where we have grader-specific pop data (currently synthetic seed; awaiting real pop data partnership).
- G10/G9 premium: ratio of Grade 10 comp to Grade 9 comp, averaged across cards.
- Times BEST · optimizer: count of optimizer cards where this grader yields the highest net profit.
- Times BEST · plays: count of plays-table cards where this grader has the top score per slug.
- Avg net per BEST submission: averaged across the cards above.
Aggregates roll up data from a small sample (16 cards on the optimizer side, ~75 cards on the plays side). They directionally represent each grader's profile but should not be treated as definitive across all card universes. Numbers will become authoritative when real pop data is integrated.
