📈 Top Investment Picks — April Update

  Player          Series    OVR   Price    Projected   ROI
  ──────────────  ────────  ────  ───────  ──────────  ────
  [Player]        Live      84🥇  3,200    → 85💎      +56%
  [Player]        Live      79🥈  1,100    → 80🥇      +354%
  [Player]        Prospect  82🥇  8,500    → 85💎      +488%

  Reasoning: Based on real-world performance trends (wOBA, FIP)
  correlated with historical attribute upgrade patterns.
```

4. Add analytical context:
   - Real-world performance driving potential upgrades (link to sabermetric data)
   - Historical price patterns around roster updates
   - Supply/demand dynamics
   - Collection impact (gate cards vs. non-gate)

## Correlation with Real-World Stats

The most valuable insight this plugin provides is connecting real-world
sabermetric performance to in-game card upgrades. A player whose real FIP
has dropped 0.5+ points since the last update is a strong upgrade candidate.

## Roster Update Schedule

- **Fridays** — Weekly roster updates (attributes, overalls)
- **Monthly** — Major content drops (new programs, flashbacks)
- Attribute changes correlate with 2-week rolling real-world performance
