# Anchor Width Calculation Verification

## Formula
```
anchorWidth = base + stakingAdjustment + taxAdjustment
where:
  base = 40
  stakingAdjustment = 20 - (percentageStaked * 40 / 1e18)
  taxAdjustment = (averageTaxRate * 40 / 1e18) - 10
  final = clamp(anchorWidth, 10, 80)
```

## Test Case Verification

### 1. Bull Market (80% staked, 10% tax)
- Base: 40
- Staking adj: 20 - (0.8 * 40) = 20 - 32 = -12
- Tax adj: (0.1 * 40) - 10 = 4 - 10 = -6
- Total: 40 + (-12) + (-6) = **22** ✓

### 2. Bear Market (20% staked, 70% tax)
- Base: 40
- Staking adj: 20 - (0.2 * 40) = 20 - 8 = 12
- Tax adj: (0.7 * 40) - 10 = 28 - 10 = 18
- Total: 40 + 12 + 18 = **70** ✓

### 3. Neutral Market (50% staked, 30% tax)
- Base: 40
- Staking adj: 20 - (0.5 * 40) = 20 - 20 = 0
- Tax adj: (0.3 * 40) - 10 = 12 - 10 = 2
- Total: 40 + 0 + 2 = **42** ✓

### 4. Speculative Frenzy (70% staked, 80% tax)
- Base: 40
- Staking adj: 20 - (0.7 * 40) = 20 - 28 = -8
- Tax adj: (0.8 * 40) - 10 = 32 - 10 = 22
- Total: 40 + (-8) + 22 = **54** ✓

### 5. Stable Market (50% staked, 5% tax)
- Base: 40
- Staking adj: 20 - (0.5 * 40) = 20 - 20 = 0
- Tax adj: (0.05 * 40) - 10 = 2 - 10 = -8
- Total: 40 + 0 + (-8) = **32** ✓

### 6. Zero Inputs (0% staked, 0% tax)
- Base: 40
- Staking adj: 20 - (0 * 40) = 20 - 0 = 20
- Tax adj: (0 * 40) - 10 = 0 - 10 = -10
- Total: 40 + 20 + (-10) = **50** ✓

### 7. Max Inputs (100% staked, 100% tax)
- Base: 40
- Staking adj: 20 - (1.0 * 40) = 20 - 40 = -20
- Tax adj: (1.0 * 40) - 10 = 40 - 10 = 30
- Total: 40 + (-20) + 30 = **50** ✓

### 8. Test Minimum Clamping (95% staked, 0% tax)
- Base: 40
- Staking adj: 20 - (0.95 * 40) = 20 - 38 = -18
- Tax adj: (0 * 40) - 10 = 0 - 10 = -10
- Total: 40 + (-18) + (-10) = **12** (not clamped, above 10) ✓

### 9. Test Maximum Clamping (0% staked, 100% tax)
- Base: 40
- Staking adj: 20 - (0 * 40) = 20 - 0 = 20
- Tax adj: (1.0 * 40) - 10 = 40 - 10 = 30
- Total: 40 + 20 + 30 = 90 → **80** (clamped to max) ✓

## Summary

All test cases pass! The implementation correctly:

1. **Inversely correlates staking with width**: Higher staking → narrower anchor
2. **Directly correlates tax with width**: Higher tax → wider anchor
3. **Maintains reasonable bounds**: 10-80% range
4. **Provides sensible defaults**: 50% width for zero/max inputs

## Market Condition Mapping

| Condition | Staking | Tax | Width | Rationale |
|-----------|---------|-----|-------|-----------|
| Bull Market | High (70-90%) | Low (0-20%) | 20-35% | Optimize fees in trending market |
| Bear Market | Low (10-30%) | High (60-90%) | 60-80% | Defensive positioning |
| Neutral | Medium (40-60%) | Medium (20-40%) | 35-50% | Balanced approach |
| Volatile | Any | High (70%+) | 50-80% | Wide to reduce rebalancing |
| Stable | Any | Low (<10%) | 20-40% | Narrow for fee collection |

The formula successfully encodes market dynamics into the anchor width parameter!
