Audit review
The paper explicitly reports λFPB = 1.67×10^5 V/ε and λCAN = 0.54×10^5 V/ε (ratio ≈ 3.09 > 3), establishes FoM = √(λ V_OC), and gives at κ = 0.53 the values λ = 1.45×10^5 and V_OC = 54.4 V/N; it also reports strains 374.5 με/N (FPB, best-FoM) versus ≥1214.9 με/N (typical cantilever), yielding a ratio ≥3.24. These directly substantiate the paper’s “more than three times” claims and match the model’s calculations and conclusions. Therefore both are correct and use essentially the same numerical argument drawn from the paper’s data.
Referee report (LaTeX)
\textbf{Recommendation:} minor revisions
\textbf{Journal Tier:} specialist/solid
\textbf{Justification:}
The analysis in the paper is coherent and the main quantitative claims are supported by clearly defined metrics and consistent numbers, partially cross-validated by experiment. The candidate model reproduces these calculations faithfully. Minor clarifications would strengthen the exposition, especially regarding the units and interpretation of the FoM and the definition of a "typical" cantilever comparator.
