What stretching actually does to your body ft. Sofie Dossi

Several people are confused about whether she meant 5 minutes per day or per week, for a given muscle group. She meant per week. 
I play recreational soccer and have a tight quad on my kicking leg. So I intend to fix it with a daily quad stretch at bedtime, for 1 minute. 
Here is the relevant section from the abstract Physics Girl referenced:   

"Time spent stretching per week seems fundamental to elicit range of movement improvements when stretches are applied for at least or more than 5 min, whereas the time spent stretching within a single session does not seem to have significant effects for ROM gains. Weekly frequency is positively associated to ROM. Evaluated data indicates that performing stretching at least 5 days a week for at least 5 min per week using static stretching may be beneficial to promote ROM improvements."
