Official Score Calculation Formula:

1. Calculate great-circle distance using Haversine formula:

   
        function haversine(lat1, lon1, lat2, lon2) {
            const R = 6371;  // Earth's radius in km
            const dLat = toRad(lat2 - lat1);
            const dLon = toRad(lon2 - lon1);
            const a = Math.sin(dLat/2) * Math.sin(dLat/2) +
                    Math.cos(toRad(lat1)) * Math.cos(toRad(lat2)) * 
                    Math.sin(dLon/2) * Math.sin(dLon/2);
            return 2 * R * Math.asin(Math.sqrt(a));
        }
        

   Formula Explanation:

   • R = 6371 km (Earth’s radius)
   • Uses great-circle distance calculation
   • Accounts for Earth’s curvature
   • Most accurate distance measurement
2. Convert distance to points using exponential decay:

   
        function calculateScore(distance) {
            return Math.round(5000 * Math.exp(-distance/2000));
        }
        

   Score Formula Explanation:

   • 5000: Maximum possible score
   • exp(-distance/2000): Exponential decay factor
   • 2000: Distance scaling factor
   • Math.round(): Rounds to nearest integer
3. Round to nearest whole number
4. Cap score between 0 and 5000 points
