Definition
A Score of 1.43 on a three-level rubric means the probability sat mostly on level 1 with some on level 2. The value is an expectation over levels, not a measurement of a real-world magnitude.
The jaggedness page is direct about this: do not interpolate between levels to reconstruct an exact number. Use the weighted score to compare against a threshold, and keep arithmetic in code.
