This third round is the real danger zone. The panel is no longer asking, “Can you explain your system?” They are asking:
“After removing the overclaims, is there still a research contribution?”
So your answer must become calm, precise, and not defensive. Do not keep retreating. You need to say: yes, the contribution is narrower, but still valid.
The uploaded third-round panel questions are mainly attacking whether anything remains after narrowing the claims.
