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 comes from the result sheets.
