Certainly. If one were to look at the tool and try to use it to determine how easy or difficult it would be to decrease the budget of National Defence by a number of billions, I don't think the tool is intended to do that.
Somebody who would want to reduce spending at DND, for example, would probably want to do a much deeper dive than just using a calculator or a tool. The tool is meant to provide an idea of how much it would cost to increase capabilities or decrease capabilities for specific military objectives, but to carry out a fulsome budget exercise, whether it be increasing funding or decreasing funding, I hope people would use something much more refined than a calculator.
It's intended to provide a tool and information for parliamentarians, but it's not meant to be used as the basis for decision-making when it comes to deciding where or how to increase or decrease funding at DND.
