Common questions
Why does the hundredths display skip some digits?
The displayed precision is 0.01 seconds, but updates follow the screen refresh rate. A 60 Hz screen updates about 60 times per second, so it cannot show every hundredth.
Are my lap records saved permanently?
Up to 100 laps are held in the current page session. Resetting or refreshing clears the records.
