So if the 57 rated boat sailed a course in 100 minutes then 100*57/100 would be corrected to 57 wouldn't it need to be more than 100 minutes? If the 84 rated boat was sailed really well and its time was also 100 minutes then it would correct out to 84. The boats would tie in head to head racing but the slower boat will lose. Or is my math skills lacking.
