Paying for timing adds a considerable expense to hosting a meet and I question whether it adds value at all when it comes to learning how to race for the high school athlete. Conditions change and times change along with them, even from the beginning or end of the day compared to the middle of the day.
My question for the coaches and athletes is how you'd feel about coming to such a meet. Can you imagine doing a race and not having an official time? The meet would still be scored properly and completely.
