Initial Benefit Assessment
N : total number of customers, e.g. 1,000,000.
T : expected fraction of target customers in the entire population, e.g. 0.03.
B : benefit of contacting a target customer (hit), e.g. $100.
- B is not uniform, but this is a useful approximation
C : cost of contacting a customer, whether a target or not (e.g. $5)
