Because there are some factors that are simply out of ones control that affect athletic ability. Should students also be graded on how much weight they can lift? How flexible they are? How far they can hit a softball? Is it fair to let that affect their GPA in districts such as mine where three years of PE (or a team sport) were a graduation requirement?

Back to the time constraint. Some teachers would FAIL students who were consistently unable to complete a mile in under 10 minutes. Effort was irrelevant. I wasn't a heavy kid, but routinely crossed the finish line bright red, gasping for breath, and light headed.

So yes, putting your student's future academic and career prospects in danger due to lower than "average" athletic ability is utter madness.
