THE JACKTOOLS.NET WAY
Timing begins at zero. Pause and resume preserve elapsed time.
Each lap shows its duration and the total time since starting.
Focus view reduces distractions. Keeping the screen awake is optional and active only while timing.
The display shows hundredths of a second. Timestamps keep timing independent of screen updates. Device clock changes, sleep mode and browser restrictions can affect measurements. Not for safety-critical or official competition timing.
