Achievable ranking accuracy under a larger assumed assay error
Finding:ceiling-2kcal of CASP16 binding affinity challenge
mean expected best Kendall's τ of 0.43 for autotaxin at 2 kcal/mol assumed error. Source wording: "Thus, if we assign an error of 30× in IC50 (2 kcal/mol in binding free energy), we obtain a mean expected best Kendall's τ of 0.43 for autotaxin, which is similar to the best result in Figure 8A."
Affinity-ranking finding stated in the body text of the CASP16 assessment.
Evidence
Source checking verifies the cited claim or transcription. It does not establish independent reproduction.

Inspect claims, sources and review details
Trace each statement to its source and review. A context-only reference supports the record generally; it does not verify an individual field. Source checking does not reproduce an experiment.
One row per statement and cited source. Multiple citations are not independent evaluations. Shared locators are labelled explicitly.

- method: source-hash-verification; pdf-text-parse; independent-cell-check; rendered-source-visual-check; ai-assisted-source-review; method note: Re-retrieved all three sources and matched each pinned SHA-256. Re-rendered the Boltz-2 supplement with pdftotext -layout (poppler 26.08.0) and matched the text layer's recorded SHA-256. Re-read all 256 cells with a parser written for this review that does not import the extraction script, matching each result to its cell through its own source_locator, and separately read appendix tables 11, 12 and 14 from PNG renderings of PDF pages 29 and 30 at 160 dpi, and Ross Table 3 from the pinned XML markup. Checked printed value, numeric value, locator, metric concept, qualifier, direction, unit, uncertainty and the linked configuration, protocol and dataset, and that every N/A or '-' cell is recorded as missing with a reason.; reviewer: claude; reviewer note: Claude review agent, independent of the extraction agent; no human review claimed; reviewed at: 2026-10-22T13:40:00Z; artifact sha256: a1d7fdc52df61c4d75197f04be91b511b7d093d229d96a0815a11f95e350256b; retrieval url: https://www.ebi.ac.uk/europepmc/webservices/rest/PMC12750038/fullTextXML; note: Independent review 2026-10-22: the quoted wording was matched against the pinned artifact and the locator checked.
