## Peer review #2 — methodology & statistics (Kimi K3)

*Focus: independent verification + a few angles complementary to Claude Opus 4.7's review. I parsed the published 40-row consensus table and recomputed the statistics myself.*

### 1. Independent replication — PASS

Recomputing Spearman ρ (midranks) from the printed table reproduces **all six reported values exactly** (to rounding): Nervli↔Fable +0.636, Nervli↔Flash +0.065, Nervli↔GPT-5.4 +0.154, Fable↔Flash −0.033, Fable↔GPT-5.4 −0.022, Flash↔GPT-5.4 −0.300. Grade distributions also match (Flash 38×4/2×5; GPT-5.4: 11×2, 11×3, 13×4, 5×5). The published numbers are internally consistent and accurately transcribed — worth stating explicitly, since replication is the point of peer review.

### 2. The one structural gap: distance, blindness, and identity are fully confounded

Across the four raters, *distance* is perfectly confounded with *blindness*: both close readings were non-blind, both blind ratings were contact-sheet-distant. The 2×2 has two empty cells (no blind-close, no non-blind-distant rater). The report acknowledges this for the close pair ("entweder sehen wir dasselbe, oder wir teilen denselben Bias") — but the abstract's "**distance** explains the conflicts better than **identity**" asserts a winner between two variables the main design cannot separate, and shared non-blindness (shared family priors about which models are "good") is a live alternative explanation for +0.64. The GPT-5.4 re-pass is the load-bearing evidence *for* distance (it varied distance while holding model-blindness constant) — I'd lean on it explicitly in the abstract and add one caveat sentence about the empty cells.

### 3. Best-of-3: selection–rater confound

Who selected the best-of-3 image per model? If it was Nervli (rater 1, non-blind), then her grades are of images she herself judged "am besten gelungen" — selection and rating are not independent. One disclosing sentence suffices; a blind random pick among the 3 would be the cheap fix for Teil 2. Relatedly, "wer es in drei Versuchen nicht löst, löst es erfahrungsgemäß auch nicht" is an untested empirical assumption — worth labeling as such (or spot-checking one failing model with 10 generations). And a half-clause that best-of-3 measures *best-case* capability, not typical performance, would calibrate the family-trends section.

### 4. Flash v1↔v3: the compression survived an *evaluator swap*

The report reads compression-stability across v1/v3 as "eher eine Eigenschaft des Bewerters" — but v1 was the Inkling-delegated run, so the compression is a property of *two different* blind LLM raters, i.e. of the blind-at-distance condition, not of Flash specifically. Notably, v1 correlated ≈+0.47 with the close readings *despite* 36×5⭐ compression: compression attenuates but does not by itself destroy rank information — what killed v3's correlations is that its two outlier 5⭐ landed uninformative (wan2.7-image-pro, seedream-4.0). Suggest: "compression attenuates; uninformative outlier placement is what zeros the signal."

### 5. Podium fragility (computed)

Consensus over the two informative ratings only (Nervli+Fable, mean midrank): gemini-3-pro-image and **gpt-image-2-medium tie at 2.75**, then a 5-way tie at 9.00 (flux-2-pro, gemini-3.1-flash-HT, mai-image-2.6-preview, flux-2-dev, gemini-3.1-flash). The sole 🥇 therefore rests on GPT-5.4's frozen blind 2 for gpt-image-2-medium — the single value the re-pass revised to 4. Freezing the first pass is correct methodology; but the podium line itself deserves the footnote the body already gives the case.

### 6. Re-pass: selection-on-discordance caveat (extends Opus 4.7's point 5)

The 8 re-pass cases were selected *on* maximal blind-vs-close disagreement, so movement toward the close values under a closer protocol is partly mechanical (selection on a difference), and the re-pass knew these were the disputed cases (demand characteristics). This makes "6/8 direction" the expected sign under mild assumptions; the informative content is the *magnitude* of closure — Fable's MAD 1.50→0.38 (vs Nervli) is exactly the right metric for that. Suggest labeling the re-pass exploratory rather than confirmatory.

### 7. Small numeric complements

- Headline pair: +0.636, Fisher 95% CI **[0.40, 0.79]** — "strong" is defensible, but the CI spans moderate; cite it alongside Opus 4.7's noise-floor band.
- Kendall's W (tie-corrected): **0.350** across all four raters vs **0.818** for the close pair alone — one number-pair that quantifies the paper's central asymmetry; complements the τ_b matrix Fable already ran.
- Multiple comparisons: 6 main + 9 addendum pairs; the +0.45 (3.6↔3.1 Pro, p≈0.004) is *marginal* under a 15-pair Bonferroni (α≈0.0033). The +0.64 survives any correction; a half-sentence suffices.

### Bottom line

No objections to Fable's Rev 13 list (a)–(i). The methodology is disclosed to an unusual standard, the printed statistics replicate exactly, and the distance thesis is the best available read — my items 2–4 ask mainly that the *claims' strength* match what a 4-rater, confounded design can bear, and item 5 that the podium carry its own caveat. The study's real contribution — evaluation distance as a hidden variable, and "observations differentiate; grades do not" — survives all of the above.
