Splitting into three axes is the right call, and your own numbers say two of the three are the same axis.
I pulled the three ELO tables off the dataset card and rank-correlated them across all 42 models:
alignment vs preference rho = 0.983
alignment vs coherence rho = 0.604
coherence vs preference rho = 0.587
Alignment and Preference are one ranking with noise on top. Coherence is the axis carrying the separating information. So the thing a single broad preference signal cannot reproduce is really Coherence, and I would lead with that rather than with three.
The sharpest case is gemini-3.7-flash: Alignment #3, Preference #2, Coherence #36. A 34-place spread, and it is the most interesting fact in the benchmark. It draws what you asked for, people like looking at it, and it is near the bottom on artifacts.
Which is why I would lift the per-axis tables out of the <details> fold on the card. The first ELO table a reader meets is "Overall ranking, aggregated across all three leaderboards", where that model sits at #10. That aggregate is the collapse your post is arguing against.
The thing I would fix first
weighted_results_image1_coherence runs backwards relative to how the card documents it.
The card says the two weighted_results_* scores "sum to 1 and give that pair's outcome on that leaderboard". True for Preference and Alignment. For Coherence the stored number is the share of annotators who picked that image for the question you actually asked, which is "which image has more glitches".
I checked against the per-vote JSON rather than assuming. 1,010 rows, read as 10 consecutive rows at each of 101 offsets evenly spaced across all 309,955:
axis decisive pairs stored tracks raw image1 vote share
coherence 624 624 / 624
alignment 633 633 / 633
preference 652 652 / 652
Near-ties dropped, since they cannot discriminate. Mean |raw - stored| is 0.022 to 0.026, which is your annotator weighting, not an inversion.
So the stored coherence value is the glitch share. Per model, against your own published ELO:
axis corr(mean stored score, published ELO) models
coherence -0.646 41
alignment +0.841 40
preference +0.811 39
Coherence is the only axis that anti-correlates with its own leaderboard, and about as strongly as the other two correlate with theirs. Your ELO is fine, you inverted it upstream. It is the published column that reads the wrong way round.
Anyone who loads this and treats weighted_results_image1_coherence > 0.5 as "image1 is cleaner" gets the coherence leaderboard upside down, and it will look plausible, because the numbers are well formed and sum to 1.
Two ways out. Rename it to something like ..._glitch, or store 1 - x so all three columns point the same way and the card sentence becomes true for all of them. I would take the second, because the failure here is silent.
Separately, the HTML-wrapping limitation at the bottom of the card is the most honest known-limitation section I have read on a benchmark this year. Keeping the affected rows in and naming the 5% is the right call.
So: was the coherence column left in raw answer space on purpose? And if the three columns were made same-direction, would you re-cut the headline table per axis instead of aggregating it?
