Starbucks Gift Card program. What determines the dollar amount?

The Starbucks Gift Card program is our want of thanking you for helping us, reach our research goal of listing "100% of the brokerage firms and their agents for NJ". The larger the firm, the bigger the Thank You. So, if the brokerage firm has 1 or 2 agents=$10, 3 agents=$15, 4 agents=$20, 5 agents=$25, 6-10 agents= $30, 11-20 agents=$40, and 21+agents=$50.
