Response correlations gave no clear site accuracy gain with five fit pulses per site and four SEEG pairs in eight patients at 50 percent weight
We tested response correlations in eight patients from the public STReEF SEEG data. Each patient had four local stimulation sites and four selected recording pairs. Five earlier pulses per site fitted the readers. Five later pulses per site tested them after recorded contact order reversal. The readers had identical pairs, site means, and marginal feature scales. At 50 percent correlation weight, correct labels changed from 115 to 116 out of 160. The mean change was +0.625 percentage points. The 95 percent patient bootstrap interval was -1.875 to +3.125 points. Feature-position permutation controls gave almost the same mean accuracy as the actual correlations. The result gives no clear evidence of a gain from full correlations in this short fitting task. It does not establish equal performance. This is an exploratory analysis in a reused cohort. The package contains code, checked public source recipes, data, fitted matrices, scores, tables, figures, and reproduction instructions. It does not test online brain interface control.

Its short-fit correlation result informed the question and the matched-scale comparison. It used a different SEEG dataset and a forecasting outcome. It supplied no input data or primary accuracy values for this study.
