Future / TODO

  1. EWMA half-life model — Per-round SG tracking with 8/24/100-round decay windows
  2. Course DNA regression — Replace manual vectors with regression-derived weights
  3. Weather wave model — NWS API, AM/PM differential for round leader edges
  4. Outright scanner — Full 150-way Shin de-vig + Monte Carlo
  5. Round Leader scanner — Requires weather wave model
  6. 3-Ball scanner — Requires tee time data
  7. Hole in One scanner — Pure probability model (par-3 count from course data)
  8. LIV-specific model — 54-hole, no-cut, 48-player fields
  9. Grass-type putting adjustment — Bermuda/Bentgrass/Poa splits (data exists in course_data)
  10. Backtesting framework — Validate model calibration
  11. DataGolf subscription — Pending boss approval ($100-250/mo) for deeper SG data
