How to Use the Stopwatch & Multi Lap Timer
- 1 Click "Start" to begin the stopwatch timer.
- 2 Click "Lap" to record sequential split lap times in the interactive log table.
- 3 Click "Pause" to stop timing, or "Reset" to return to zero.
- 4 Review recorded laps highlighting the fastest lap (green) and slowest lap (amber).
Methodology & Algorithmic Standards
Uses high precision `performance.now()` timestamp differentials rather than naive `setInterval()` counting, eliminating background browser tab throttling and timing drift.
Frequently Asked Questions
Does the stopwatch lose accuracy if I switch browser tabs? ▼
No. By calculating elapsed time using `performance.now()` wall-clock timestamps rather than counting tick intervals, the stopwatch maintains sub millisecond precision even when backgrounded.
Can I export my recorded lap times to Olevx Notepad? ▼
Yes! Click "Open in Notepad" to create a structured note with all recorded laps and overall split times.
Is there a keyboard shortcut to start/lap? ▼
You can press Spacebar to toggle Start/Pause and Enter to record a split lap.
