Can you explain more on “Annual Savings”? That sounds open to interpretation.

Each month your wireless carrier(s) dynamically charge you for services and features that change constantly. At the same time, your wireless communication needs are evolving. We identify significant areas that need to be adjusted (part of our 30 Point Analysis Program) and report them to you. These monthly adjustments, averaged from the previous three months of invoices, are then annualized and form the “Annual Savings”.
