Your plan steps down gradually, so each week has its own target on the way to your ideal.
For example, if you're going from about 25 drinks a week towards about 5, an early week might have a target of around 22, the next around 18, and so on down.
Each week is scored against that week's target. Your ideal is where the plan is heading. Once you reach your ideal, the two numbers are the same.
