## 🎯 What's in the Data

**200 data points** @ 5-minute intervals

### Key Events to Watch For:

#### 1. **Morning Hypo Risk** (6:00 AM - 7:20 AM)
- Glucose drops from 95 → 80 mg/dL
- **Alert should trigger** around 7:15 AM
- **Breakfast bolus**: 45g carbs + 4.5u insulin at 7:20 AM
- Recovery to 128 mg/dL

#### 2. **Post-Breakfast Spike** (7:20 AM - 8:30 AM)
- Glucose rises to 128 mg/dL
- Gradual descent back to normal range

#### 3. **Morning Exercise** (10:30 AM - 12:00 PM)
- Heart rate increases (65 → 130 BPM)
- Steps accumulate rapidly
- Glucose stays stable due to activity

#### 4. **Lunch Spike** (12:00 PM - 1:15 PM)
- **Large meal**: 60g carbs + 6u insulin
- Glucose spikes to **176 mg/dL** (near hyper threshold)
- **Alert should trigger** around 1:00 PM
- Gradual descent over 3 hours

#### 5. **Late Afternoon Stability** (3:00 PM - 6:00 PM)
- Glucose stable in target range (100-110 mg/dL)
- Minimal significance scores expected

#### 6. **Dinner** (6:00 PM - 7:00 PM)
- 55g carbs + 5.5u insulin
- Moderate spike to 159 mg/dL
- Controlled descent

#### 7. **SEVERE HYPO EVENT** ⚠️ (10:00 PM)
- **CRITICAL**: Glucose drops to **15 mg/dL**!
- Overcorrection with 3u insulin (mistake scenario)
- **Multiple alerts expected**
- Emergency 15g carbs consumed
- Recovery to safe levels

#### 8. **Overnight Stability** (11:00 PM onwards)
- Glucose settles around 100 mg/dL
- Normal sleep HR (52-60 BPM)

## 🧪 Expected Results

### Activation Patterns:
- **High activation**: During hypo (7:15 AM, 10:00 PM), hyper (1:00 PM)
- **Low activation**: Stable periods (3-6 PM, after 11 PM)
- **Target activation rate**: ~15-20% overall

### Alerts Expected:
Approximately **3-5 high-risk alerts**:
1. Morning hypo warning (~7:15 AM)
2. Lunch hyper warning (~1:00-1:15 PM)
3. **CRITICAL hypo** (~10:00-10:20 PM) - multiple alerts

### Energy Savings:
- **~80-85%** energy saved vs always-on
- Most savings during stable periods
- More activations during risk events

### Significance Components:
Watch how they change:
- **Glycemic deviation**: High during hypo/hyper
- **Velocity risk**: Spikes during rapid changes
- **IOB risk**: High after insulin doses
- **COB risk**: High after meals
- **Activity risk**: Elevated during exercise
- **Variability**: Shows instability during events

## 🔍 What to Look For

### 1. Performance Dashboard
- Total events: **200**
- Activations: **30-40** (15-20%)
- Energy savings: **80-85%**
- Alerts: **3-5**

### 2. Glucose Chart
- See the full day pattern
- Identify meal spikes
- Spot hypo events

### 3. Significance vs Threshold
- **Watch the PI controller adapt!**
- Threshold moves to maintain 15% activation
- Significance spikes during risk events

### 4. Energy Level
- **Bio-inspired regeneration** visible
- Drops during activations
- Regenerates during idle periods
- Should fluctuate, not flat

### 5. Significance Components
- **6 colored lines** showing risk factors
- Glycemic deviation dominates during extremes
- Velocity spikes during rapid changes
- IOB/COB after meals

### 6. Alerts Table
Look for warnings around:
- 7:15 AM (morning hypo approach)
- 1:00 PM (post-lunch hyper)
- 10:05-10:20 PM (critical hypo)

### 7. Bootstrap Confidence Intervals
- F1 Score with 95% CI
- Precision with 95% CI
- Recall with 95% CI
- Check that CI ranges are reasonable
