Mark Conversion

Races that are totally timed by a computer system (FATFully Automatic Timing) have the most accurate results. While these times are the most accurate, they are not directly comparable to times obtained with a human controlled timing system. FAT timers start right when the gun goes off, where as humans have a measurable reaction delay. 

For all performance lists, Athletic.net has chosen to convert all hand timed results into values that are generally accepted as being comparable to FAT times. Converted times are denoted by the 'c' that follows the time, while FAT times are denoted by an 'a' and followed by a 'w' if the time was wind-aided. Raw hand times are sometimes seen on meet results pages, denoted by an 'h'.

Athletic.net's conversion process, following the lead of Track & Field News:

  • Round mark up to nearest 10th/second (as is standard procedure with hand times)
  • add 0.24s for races less than 300m
  • add 0.14s for races 300m to 400m

 

Example

Here is an example to explain how the system works. Let's say that you are at a meet where the races are hand timed. (No finish line camera, or, the camera system was not working for this race). 

  • The athlete runs a hand-timed 12.82 second 100m.
  • The first step is to round up the time to the next tenth of a second. 12.82 --> 12.9
  • Next, a conversion factor is added: +0.24s. So, our 12.9 --> 13.14c
  • A 'c' is added to the converted mark to indicate that it has been converted. 


Coaches are instructed to not perform any conversions prior to entering marks into Athletic.net. Conversions are automatically performed on all marks in a consistent fashion. This helps insure that the conversions are done correctly, and that the performance lists are as fair as possible.
