Are comparisons based on superannuation fund-level performance useful?

Are comparisons based on superannuation fund-level performance useful?

The Australian Prudential Regulation Authority has published audited, superannuation fund performance information for around 20 years, including a time-series of fund-level rates of return since 2009. Fund-level performance information has been used by APRA and others for comparisons, including comparisons of different sectors of the superannuation system, such as industry super funds and retail super funds.
Research houses, government reviews, policy advocates, and many others also use this information to understand the superannuation system better.

The appropriateness of these comparisons is, however, contested.
