## Analysis

### Scoring

1. **Per-Scenario Average**: Average rating for each scenario across all users
2. **Per-User Average**: Average rating for each user across all scenarios
3. **Overall Average**: Average of all ratings (target: 4.0+)

### Success Criteria

- ✅ **PASS**: Overall average ≥ 4.0

- More than 20% of users rate 1-2 (quality problem)
- Trust/action rates < 70% (credibility issue)
- Consistent complaints about specific insight type

## Common Issues and Solutions

### Issue 1: Generic Insights

**Symptoms**: Users rate 3 or lower, comment "too generic"

**Root Cause**: Insufficient context or over-simplified prompts

**Solution**:
- Enhance system prompts with more context
- Add user demographics to LLM context
- Increase few-shot examples for personalization

### Issue 2: Inaccurate Math

**Symptoms**: Users rate 2 or lower, comment "wrong calculations"

**Root Cause**: LLM hallucinating numbers instead of using local functions

**Solution**:
- Ensure all math done by local functions (not LLM)
- LLM only provides reasoning around pre-calculated results
- Add validation layer for numerical outputs

### Issue 3: Context Loss in Conversation

**Symptoms**: Multi-turn conversations rated < 3

**Root Cause**: Context not preserved or cache issues

**Solution**:
- Increase conversation context window
- Verify cache TTL (should be 24h)
- Add conversation history to each turn

### Issue 4: Risk-Averse Advice

**Symptoms**: Users comment "too conservative" or "not helpful"

**Root Cause**: Over-tuned safety prompts

**Solution**:
- Balance safety with actionability
- Include disclaimers without being overly cautious
- Provide range of options (conservative to aggressive)
