The author emphasizes that the **ECI results** themselves aren't the issue; the key is understanding that they are measurements within the **IRT** (Item Response Theory) framework, and score differences shouldn't be taken as absolute indicators of superiority.

When interpreting these leaderboards, uncertainty and statistical error must be factored in.
