 ### Comprehensive Benchmark Results
 
 **Selected checkpoint:** `step_1000`  
-**Overall weighted evaluation score:** `0.710`
+**Best `eval_accuracy`:** `0.710`
 
-The checkpoint was selected by evaluating all checkpoints from step 100 through step 1000 across the 15 benchmark categories. The overall score uses the weighting defined in the project evaluation harness, with additional emphasis on reasoning, code generation, question answering, instruction following, and safety.
+The checkpoint was selected strictly by comparing `eval_accuracy` for every checkpoint found in the workspace. `step_1000` had the highest value.
