What it measures vs what it misses
✓ Measures
Knowledge-answer correctness.
✗ Misses
Adjacent capabilities, subjective preference, latency, and cost.
Why this countsIt tests whether the model is actually useful in normal conversational turns, not just on narrow correctness tasks.Same-test ruleThis percentile only compares models inside the exact benchmark/version group shown here. It is not a universal score.What it missesIt does not prove deeper reasoning, tool use, or enterprise workflow reliability.
