🎯 Purpose

• This tool standardizes how drive day data is recorded and analyzed across the team.
• It replaces inconsistent spreadsheets and ensures reliable, structured data collection.

🚀 Features

• Driver-based lap tracking
• Automatic lap creation
• Best & average time calculations
• Penalty system:
  • +2s per cone
  • +20s per missed gate
• Session metadata:
  • Event type (Skidpad, Autocross, Endurance, Kart)
  • Weather & track conditions
  • Start/end times
  • Total distance
• Tire data logging
• State of Charge (SOC) tracking
• Track image upload
• Local persistence
• Advanced driver statistics (consistency, penalties, penalties per lap)
• Session leaderboard for quick driver comparison
• Session-wide averages for performance analysis
• Export run sheet as formatted PDF for sharing and archiving

🏁 Drive Day Workflow

1. Add drivers
2. Record laps (live or manual)
3. Input penalties during laps
4. Fill in session metadata
5. Export

🧠 Timing Logic

• If one lap is entered, used directly
• If two laps are entered, average is used
• Penalties are applied after base time calculation

$$Final Time = baseTime + (2 \times cones) + (20 \times offtrack)$$

⚠️ Data Storage

• Data is now stored in Firebase (cloud)
• Sessions are shared across devices in real-time
• Internet connection required

🏗️ Architecture

• Frontend: React + TypeScript (Vite)
• Backend: Firebase Firestore (real-time database)
• Deployment: Vercel

The system uses a session-based architecture where:

• A host creates a session
• Others join via code
• All updates sync instantly via Firestore listeners
