Does changing a Goal alter past measurements?
Targets and observations are separate; changed targets affect interpretation, not the original measured result.
Method and interpretation
A Goal sets a benchmark; it does not alter observations. Define a valid positive target for each metric and calculate current ÷ target × 100. For example, a current rate of 35% against a 70% target means 50% attainment, not 35% attainment.
