Lap Time vs Split Time

Understanding the difference:

• Lap Time: Time for individual lap (e.g., Lap 2: 45 seconds)
• Split Time: Total cumulative time from start (e.g., Total: 2:15)
• Example: In a 3-lap race - Lap 1: 1:00, Lap 2: 1:10, Lap 3: 1:05 → Total: 3:15

Tips for Accurate Timing

• Browser Tab: Keep tab active for most accurate timing
• Anticipate: Start stopwatch slightly before actual event
• Lap Early: Press lap button in advance to account for reaction time
• Background Noise: Disable browser notifications for better focus

💡 Pro Tip: For competitive timing (like speedruns), use the keyboard shortcuts instead of clicking buttons. Space bar for start/stop and L for laps provides faster reaction time and more accurate splits!
