Subclaims¶
Reading the evidence codes
q is the design tier, i the impact, n the sample, and the kind with its r
the rigour judged within that kind: what each code means.
This claim: no standardized effect is recorded in observations/ for it yet, so no benchmark reading is possible.
q2 i? GPT-4o-scored narration quality shows PIVOT highest (Overall 0.89) versus TheoremExplainAgent (0.84) and Code2Video (0.75). → Xinchen Ma 2026

q2 · i? · design · r2
Narration fields extracted from generated scripts were independently scored by GPT-4o on Accuracy and Depth and Logical Flow (0-1), with the final transcript score as their arithmetic mean; the table shows "PIVOT0.87 0.91 0.89". No statistical test is reported.
