# Achieving Strong Baseline Metrics

**Purpose**: How to achieve V_meta(s₀) ≥ 0.40 for rapid convergence
**Impact**: Strong baseline reduces iterations by 2-3 (40-60% time savings)

---

## V_meta Baseline Formula

```
V_meta(s₀) = 0.4 × completeness +
             0.3 × transferability +
             0.3 × automation_effectiveness

Where (at iteration 0):
- completeness = initial_coverage / target_coverage
- transferability = existing_patterns_reusable / total_patterns_needed
- automation_effectiveness = identified_automation_ops / automation_opportunities
```

**Target**: V_meta(s₀) ≥ 0.40

---

## Component 1: Completeness (40% weight)

**Definition**: Initial taxonomy/pattern coverage

**Calculation**:
```
completeness = initial_categories / estimated_final_categories
```

**Achieve ≥0.50 by**:
1. Comprehensive data analysis (3-5 hours)
2. Create initial taxonomy (10-15 categories)
3. Classify ≥70% of observed cases

**Example (Bootstrap-003)**:
```
Iteration 0 taxonomy: 10 categories
Estimated final: 12-13 categories
Completeness: 10/12.5 = 0.80

Contribution: 0.4 × 0.80 = 0.32 ✅
```

---

## Component 2: Transferability (30% weight)

**Definition**: Reusability of existing patterns/knowledge

**Calculation**:
```
transferability = (borrowed_patterns + existing_knowledge) / total_patterns_needed
```

**Achieve ≥0.30 by**:
1. Research prior art (1-2 hours)
2. Identify similar methodologies
3. Document reusable patterns

**Example (Bootstrap-003)**:
```
Borrowed from industry: 5 error patterns
Existing knowledge: Error taxonomy basics
Total patterns needed: ~10

Transferability: 5/10 = 0.50

Contribution: 0.3 × 0.50 = 0.15 ✅
```

---

## Component 3: Automation Effectiveness (30% weight)

**Definition**: Early identification of automation opportunities

**Calculation**:
```
automation_effectiveness = identified_high_ROI_tools / expected_tool_count
```

**Achieve ≥0.30 by**:
1. Analyze high-frequency tasks (1-2 hours)
2. Identify top 3-5 automation candidates
3. Estimate ROI (>5x preferred)

**Example (Bootstrap-003)**:
```
Identified in iteration 0: 3 tools
  - validate-path.sh: 65.2% prevention, 61x ROI
  - check-file-size.sh: 100% prevention, 31.6x ROI
  - check-read-before-write.sh: 100% prevention, 26.2x ROI

Expected final tool count: ~3

Automation effectiveness: 3/3 = 1.0

Contribution: 0.3 × 1.0 = 0.30 ✅
```

## Worked Example: Bootstrap-003

### Iteration 0 Investment: 120 min

**Data Analysis** (60 min):
- Queried session history: 1,336 errors
- Calculated error rate: 5.78%
- Identified frequency distribution

**Taxonomy Creation** (40 min):
- Created 10 initial categories
- Classified 1,056/1,336 errors (79.1%)
- Estimated 2-3 more categories needed

**Pattern Research** (15 min):
- Reviewed industry error taxonomies
- Identified 5 reusable patterns
- Documented error handling best practices

**Automation Identification** (5 min):
- Top 3 opportunities obvious from data:
  1. File-not-found: 250 errors (18.7%)
  2. File-size-exceeded: 84 errors (6.3%)
  3. Write-before-read: 70 errors (5.2%)

### V_meta(s₀) Calculation

```
Completeness: 10/12.5 = 0.80
Transferability: 5/10 = 0.50
Automation: 3/3 = 1.0

V_meta(s₀) = 0.4 × 0.80 +
             0.3 × 0.50 +
             0.3 × 1.0

           = 0.32 + 0.15 + 0.30
           = 0.77 ✅✅ (far exceeds 0.40 target)
```

**Result**: 3 iterations total (rapid convergence)

---

## Contrast: Bootstrap-002 (Weak Baseline)

### Iteration 0 Investment: 60 min

**Coverage Measurement** (30 min):
- Ran coverage analysis: 72.1%
- Counted tests: 590
- No systematic approach documented

**Pattern Identification** (20 min):
- Wrote 3 ad-hoc tests
- Noted duplication issues
- No pattern library yet

**No Prior Research** (0 min):
- Started from scratch
- No borrowed patterns

**No Automation Planning** (10 min):
- Vague ideas about coverage tools
- No concrete automation identified

### V_meta(s₀) Calculation

```
Completeness: 0/8 patterns = 0.00 (none documented)
Transferability: 0/8 = 0.00 (no research)
Automation: 0/3 tools = 0.00 (none identified)

V_meta(s₀) = 0.4 × 0.00 +
             0.3 × 0.00 +
             0.3 × 0.00

           = 0.00 ❌ (far below 0.40 target)
```

**Result**: 6 iterations total (standard convergence)

## Quick Assessment: Can You Achieve 0.40?

**Question 1**: Do you have quantitative data to analyze?
- YES: Proceed with completeness analysis
- NO: Gather data first (delays rapid convergence)

**Question 2**: Does prior art exist in this domain?
- YES: Research and document (1-2 hours)
- NO: Lower transferability expected (<0.20)

**Question 3**: Are high-frequency patterns obvious?
- YES: Identify automation opportunities (1 hour)
- NO: Requires deeper analysis (adds time)

**Scoring**:
- **3 YES**: V_meta(s₀) ≥ 0.40 achievable (5-9 hours)
- **2 YES**: V_meta(s₀) = 0.30-0.40 (7-12 hours)
- **0-1 YES**: V_meta(s₀) < 0.30 (not rapid convergence candidate)

## Common Pitfalls

### ❌ Insufficient Data Analysis

**Symptom**: Analyzing <50% of available data
**Impact**: Low completeness (<0.40)
**Fix**: Comprehensive analysis (3-5 hours)

**Example**:
```
❌ Analyzed 200/1,336 errors → 5 categories → completeness = 0.38
✅ Analyzed 1,336/1,336 errors → 10 categories → completeness = 0.80
```

---

### ❌ Skipping Prior Art Research

**Symptom**: Starting from scratch
**Impact**: Zero transferability
**Fix**: 1-2 hours research

**Example**:
```
❌ No research → 0 borrowed patterns → transferability = 0.00
✅ Research industry taxonomies → 5 patterns → transferability = 0.50
```

---

### ❌ Vague Automation Ideas

**Symptom**: "Maybe we could automate X"
**Impact**: Low automation score
**Fix**: Concrete identification + ROI estimate

**Example**:
```
❌ "Could automate coverage" → automation = 0.10
✅ "Coverage gap analyzer, 30x speedup, 6x ROI" → automation = 0.33
```

---

## Measurement Tools

**Completeness**:
```bash
# Count initial categories
initial=$(grep "^##" taxonomy.md | wc -l)

# Estimate final (from analysis)
estimated=12

# Calculate
echo "scale=2; $initial / $estimated" | bc
# Target: ≥0.50
```

**Transferability**:
```bash
# Count borrowed patterns
borrowed=$(grep "Source:" patterns.md | grep -v "Original" | wc -l)

# Estimate total needed
total=10

# Calculate
echo "scale=2; $borrowed / $total" | bc
# Target: ≥0.30
```

**Automation**:
```bash
# Count identified tools
identified=$(ls scripts/ | wc -l)

# Estimate final count
expected=3

# Calculate
echo "scale=2; $identified / $expected" | bc
# Target: ≥0.30
```
