Texas Track & Field 2004
(rules adopted by U.I.L.)

 

Rule: 3-9-4 ...Electronic or digital timers which measure one one-hundredth of a second must be used.  However, unless it is a fully automatic system, times registered in one one-hundredth of a second shall be rounded up to the next tenth of a second.  (Example: 10.42 will be recorded as 10.5 unless a FAT system is used.)  If FAT and manual times must be integrated, the hand-held times shall first be rounded up to the slower one-tenth of a second. Then a conversion factor of .24 must be added (i.e., MT +.24 = FAT)
