🏆 Scoring System

📊 Score Calculation

Your session score is calculated using the formula:

Score = Character Speed (WPM) × Accuracy (%)

This means higher speeds are rewarded, but only when coupled with good accuracy.

Example: Good Performance

  • Character Speed: 20 WPM
  • Correct: 22/25 (88% accuracy)
  • Score: 20 × 0.88 = 17.6 points

Example: High Speed

  • Character Speed: 30 WPM
  • Correct: 18/25 (72% accuracy)
  • Score: 30 × 0.72 = 21.6 points

💡 Tips & Best Practices

🎯 For Beginners

  • Start with slower speeds (10-15 WPM) to build accuracy first
  • Begin with 3-character or 4-character callsign difficulties for easier copying
  • Use shorter sessions (10-25 callsigns) to build confidence gradually
  • Focus on recognizing callsign patterns and prefixes
  • Watch the progress indicator to track your improvement during sessions
  • Don't worry about perfection - even experienced ops make mistakes
  • Use the repeat button if you miss part of a callsign
  • Practice regularly with short sessions rather than marathon training

🚀 For Intermediate Users

  • Gradually increase character speed to challenge yourself
  • Progress from 4-character to 5-character and 6+ character difficulties
  • Use medium sessions (50-75 callsigns) for sustained practice
  • Add QRM interference (S2-S4) to simulate real-world conditions
  • Learn common callsign prefixes to predict the rest
  • Practice writing callsigns as you hear them (muscle memory)
  • Pay attention to rhythm - callsigns have natural flow patterns
  • Set personal goals for accuracy at specific WPM levels

⚡ Advanced Training

  • Challenge yourself with higher speeds (25+ WPM)
  • Use "🌍 All Callsigns" difficulty for maximum unpredictability
  • Train with longer sessions (100-200 callsigns) for endurance
  • Add heavy QRM interference (S5-S9) for extreme conditions
  • Practice portable callsigns with "/" characters for complexity
  • Focus on maintaining accuracy under pressure
  • Practice with contest-like conditions (fast recognition)
  • Use pause/resume strategically to manage fatigue
  • Track your progress in the statistics to see improvement

📈 Progress Tracking

  • Complete regular sessions to build your statistics database
  • Monitor your accuracy trends over time
  • Set speed goals and work toward them gradually
  • Use the live results table to identify problem areas
  • Celebrate improvements in both speed and accuracy
