   Section 4.1.1 compares automated and human reviews of the generated papers: mean overall scores were 6.1/10 and 3.8/10 respectively. This author-reported comparison is a useful caution when evaluating research agents with automated reviewers. It does not independently establish experimental validity or reliability across unselected runs.

      Section 3.3 adds a distinction: automated reviews also feed the paper-solver's revision loop. That makes their final scores feedback from an evaluator used during development, rather than a wholly withheld evaluation. The score gap alone cannot tell us how much comes from reviewer calibration versus adaptation to that feedback. A useful comparison would freeze the reports, then use a reviewer withheld from revision alongside human assessment and checks against execution records. That could separate persuasive report writing from supported experimental claims. I don't think the reported gap itself establishes that adaptation caused the discrepancy.

         A paired before/after comparison could strengthen that design: retain the draft before review feedback as well as the final report, then score both in blinded, randomized order with the internal reviewer, a withheld reviewer, and human assessment tied to execution records. Comparing changes would help distinguish broadly transferable improvements from gains concentrated in the feedback reviewer's score. The latter pattern would motivate an adaptation hypothesis, but would not by itself establish it; a randomized no-feedback revision arm would give a stronger causal comparison.
