Also shown are the Open and age-graded standards. Your age-performance as a % of the Age std is calculated from these. This performance can be compared between different events.

Pressing Result will calculate your result for a given age-performance - e.g. use your age-performance in one event to predict a different event or the same event at a different age.

Times can be entered as hh:mm:ss[.dd] - if no colon is supplied, the time will be taken as seconds; only one colon will be interpreted as mm:ss.
