- Side-by-side swing comparison: load a pro's swing video and see where your hip-shoulder timing diverges
- Drill-of-the-week picker based on the single biggest flaw detected in your last 10 swings
- Progress dashboard showing rotation angle, swing speed proxy, and consistency over the last 30 days
