How does pa.getGap calculate the target gap?

The target gap is calculated to indicate how far the current score is from the target value. When evaluating gaps for maximize indicators, the function uses the relationship between the current score and the desired target outcome. Here, the calculation approach involves subtracting the target from the score, represented as Score - Target.

In scenarios involving maximize indicators, you're aiming to understand how much the current score falls short of achieving the desired target. This method reflects that if the score is below the target, the resulting gap is negative, expressing a deficit in achieving the goal. This is essential for making informed decisions on performance improvements or adjustments required to reach the target.

In contrast, other options suggest different arithmetic operations which do not yield the correct interpretation of the target gap in the context of maximize indicators, thus they do not align with the intended calculation for assessing the performance gap correctly.
