When I was in high school (4 years ago) we only ran the 40 once, maybe twice a year during the offseason.
The off season weight program was well monitored though. We recorded everything we did in the weight room on sheets that specified our workouts for that day if we lifted 3 times a week we might have 3 different workout sheets for each day, all that varied in terms of the lifts that we did. The weight and how many reps we did in each specific lift was recorded and turned in at the end of the workout
Might look something like this..
