Each day you need to count both how many connections you sent out from each sales rep and how many who accepts the conenction (See more about this in Step 5). This statistic is noted in this document: Connections - Linkedin.
When a new Sales Rep start, you add them to the list, and if a sales rep stop, you remove them from the list. (NOT their history and the connections that has been made, just for future statistic.)
In the first tab: "Connecting Overview" you note the numbers,
In the second tab: "Sales Reps - Network" you can see what network each sales rep is working on. If it changes, it will be updated with a date, and then you just change the name of the network in the first tab.
