In Update #1, you get 4 "work points" for each time you work. Each job has a deadline. The job will tell you it needs to be done by, for example, day 20. You can work three times a day. That's 12 points per day. If it is day 16 in the morning, that means you have 5 days to work if you work all the time to complete the job by the end of day 20, which means 60 (5 days * 3 times per day * 4 points) is the maximum you can do at that time.
It's best to start a job on Monday morning, as that refreshes the jobs, starts the week of rent, and usually the apartment is empty often on Mondays and Tuesdays.
