Every Monday, you will go into Caselink and scrape cases from the previous week (Sunday through Saturday).
You have the option to pull whenever you want during the month. However you will need to pull records for every day that you didn't pull records.
For instance, you pull records on 6/20/2017. Then you don't pull any records for 10 days. When you pull records on 6/30/2017, you will need to be sure that you pull records for 6/21/2017 -> 6/30/2017. This ensures that no records are missed.
