I was comparing police and movie because those have the same lengths of shift.
Shortest police 37 s, shortest movie 1 min.
Longest police 93 mins, longest movie 80 mins.
The next shortest is 3 mins, then 6 mins. Movie doesn't have a 9 min task. Movie has 19m but police jumps to 37. And then yes movie has 31 and 49.
I'm maxed out on everything, including employees (lvl 10). I did a little test and on average it took an employee 72 minutes to finish 1 person for police helping 25 people. If I were to only help 15 people it would be 80 mins on average.
Now with movie employees it took on average 75 minutes to help 1 person.
I do use lps on tasks that take longer than 1 hour for both professions. I had more people in police needing the 1.5 hour task than I did in the movie needing 1 hr 20 m task, 4/15 for police required over 2 hours for tasks while only 2/15 required 2 hours in police.
