Race performance plotter
Date must be in the form mm/dd/yy with 2 digits for mm, dd and yy.
The dates must also be in chronological order. If this is not done the plotter
just assumes 3 days between each race. ex. 04/08/94 NOT! 4/8/94
Distance and Time formats are like PF
calculation (you can add k, and have hr:min:sec or just have mmss for minutes
and seconds).
