The line is %GMT: the winner's time divided by this athlete's, so 100% is winning pace and higher is better. It is the only number that compares across years, venues and conditions; the raw time is printed on each point because that is the one a paddler recognises. A dashed segment skips seasons with no results, and the grey tick is that season's median. ▽ marks a time so far off this athlete's best it is almost always a garbled source time.

Under the line is the season's best placement, with its round: 4th in an A final beats 1st in a B final. "A·9" is an A final with nine boats.

Seasons are labelled by age on Dec 31 of that year, the way age classes count it. The birth year is estimated from the age classes raced, so an age marked ~ can be one year high for an athlete who always raced up.
