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)


Achieving V_meta(s₀) ≥ 0.40: Checklist

Completeness Target: ≥0.50

Tasks:

  • Analyze ALL available data (3-5 hours)
  • Create initial taxonomy/pattern library (10-15 items)
  • Classify ≥70% of observed cases
  • Estimate final taxonomy size
  • Calculate: initial_count / estimated_final ≥ 0.50?

Time: 3-5 hours Contribution: 0.4 × 0.50 = 0.20


Transferability Target: ≥0.30

Tasks:

  • Research prior art (1-2 hours)
  • Identify similar methodologies
  • Document borrowed patterns (≥30% reusable)
  • List existing knowledge applicable
  • Calculate: borrowed / total_needed ≥ 0.30?

Time: 1-2 hours Contribution: 0.3 × 0.30 = 0.09


Automation Target: ≥0.30

Tasks:

  • Analyze task frequency (1 hour)
  • Identify top 3-5 automation candidates
  • Estimate ROI for each (>5x preferred)
  • Document automation plan
  • Calculate: identified / expected ≥ 0.30?

Time: 1-2 hours Contribution: 0.3 × 0.30 = 0.09


Total Baseline Investment

Minimum: 5-9 hours for V_meta(s₀) = 0.38-0.40 Recommended: 6-10 hours for V_meta(s₀) = 0.45-0.55 Aggressive: 8-12 hours for V_meta(s₀) = 0.60-0.80

ROI: 5-9 hours investment → Save 10-15 hours overall (2-3x)


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

Transferability:

# Count borrowed patterns

# Estimate total needed
total=10

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

Automation:
