## Performance Grading System

### Overall Score Calculation
```typescript
const scores = {
  load: initialRenderTime < 3000 ? 20 : 0,      // 20 points
  pan: panFPS > 30 ? 20 : 0,                     // 20 points
  zoom: zoomFPS > 30 ? 20 : 0,                   // 20 points
  selection: selectionTime < 100 ? 20 : 0,       // 20 points
  lod: lodTransitionTime < 100 ? 20 : 0,         // 20 points
};
// Total: 100 points
```

### Grade Distribution
- **A (90-100)**: Production ready, excellent performance
- **B (70-89)**: Good performance, minor optimizations needed
- **C (50-69)**: Acceptable, optimization work required
- **D (30-49)**: Below target, significant optimization needed
- **F (0-29)**: Not viable, major architectural changes needed

## Success Criteria

A successful baseline benchmark run should:

1. ✅ Complete all 5 scenarios without errors
2. ✅ Generate valid JSON results file
3. ✅ Generate HTML report with charts
4. ✅ Show performance grade (A-F)
5. ✅ List any blockers preventing production
6. ✅ Provide actionable recommendations
7. ✅ Capture accurate environment details
8. ✅ Save timestamped results for comparison

## Next Steps

1. **Run the baseline benchmark** to establish current performance
2. **Review the HTML report** to identify optimization opportunities
3. **Track metrics over time** as optimizations are implemented
4. **Compare against targets** to measure progress
5. **Integrate into CI/CD** for regression detection
