Reliability

Last updated 30 October 2023

We seek feedback and advice about how we estimate the gap from our external and internal subject matter experts. The reliability for this estimate is high with a score of 25.

As with all gap estimates, the PSO gap estimate remains sensitive to assumptions. We will continue to monitor and test the overall approach as we improve it in future releases.

"Figure 3: This image shows a graph that represents the reliability rating for the current Alcohol tax gap estimate. The rating scale includes:
-          Very low which is a score between 0 and 10
-          Low which is a score between 11 and 15
-          Medium which is a score between 16 and 20
