Units

What it's for

What the numbers on the desk, the sheets and the FIS files mean, and how they are written.

The rules

• Run times are truncated to 1/100 s, never rounded. 48.889 s is written 48.88. A sum of runs is made from the truncated run times.
• Times of day are written HH:MM:SS.ssss, four decimals, truncated to 1/10 000 s, as the FIS timing report asks.
• A time is never changed. What the device sent is what is stored; see What is never changed automatically.
• A hand time is marked *HT and comes only from the calculator in Modify data; see Modify data and hand time. The correction is rounded to the precision of System A's time of day.
• Time zones never affect timing. An impulse is filed by which race and run was green when it arrived, nothing else.
• Speeds are stored in km/h and lengths in metres. The account's unit setting (metric or imperial) changes only what is shown and typed: km/h or mph, m or ft. A speed on the desk has two decimals; on a live surface it is a whole number.
• Penalties and points are worked in whole hundredths; the penalty rounds half-up at the third decimal (art. 4.4.8). See Penalty calculation.
