Calculate how long a workout will last

When I was planning the first week of hypertrophy training for my friend I realized that I had no idea how long a workout session would last.
So, I tried to come up with some sort of formula that could roughly predict the total time of the workout.
After various attempts, I have this formula that has a 10 min range of error (between my prediction and the actual time that my friend has been training):


set.tot is the total amount of sets in the session.
1.55 is an estimation of the duration of a single set plus the rest between set. 1 min of rest between sets and more or less 30 second to complete one set (1+ 0.55)
25 includes the time for warm-up, cool-down, stretching and some setbacks that may happen in the gym, for istance waiting to use the bench press

This formula helps me a lot when I'm a workout, especially if my friend has to go to the gym between classes.
