Example. The AIME 128-sample measurement record [ftip-00A6]
[clay2026demystifying, Section 5.1, Table 2] reports the following empirical target-answer rates for AIME Problem 4 with Qwen2.5-7B-Instruct and evaluation size \(m=128\). The task asks for the number of integer pairs \((x,y)\in [-100,100]^2\) satisfying \(12x^2-xy-6y^2=0\); the target answer is \(117\).
\[ \begin {array}{c|ccc} &\mathrm {SFT{+}}&\mathrm {Base}&\mathrm {SFT{-}}\\ \hline \text {No Reward}&26.6&3.92&0.00\\ \text {Sparse Reward}&85.9&10.2&0.00\\ \text {Dense Reward}&86.7&92.2&0.00 \end {array} \]Every entry in the displayed array is a percentage.
These are source-reported empirical percentages, not exact policy probabilities. ``No Reward'' is retained as the source's row label; the table alone does not define it as a post-training protocol. The three zero entries for SFT-negative are finite observations and remain subject to Remark [ftip-00A0]. Appendix Figure 5's caption prints a different set of Qwen2.5-7B-Instruct values that duplicates the neighbouring movie-quote caption and is incompatible with Table 2. The displayed percentages are those of Table 2; the caption does not provide a consistent alternative measurement.
