A two-pulse site rank did not show lower 20–100 ms SEEG forecast error than a spread budget in five sessions
We tested whether two early SEEG responses can assign a fixed calibration budget. The public sample was OpenNeuro ds004457 version 1.0.2. It contained 182 stimulation sites, 15 recording pairs, and 728 test pulses in five sessions. The rank gave four calibration pulses to about half the sites and two to the other sites. A reference spread the same 542-pulse budget as evenly as possible. We scored centered voltage from 20 to 100 ms. The mean patient error reduction against the spread reference was -0.55%. The 95% patient bootstrap interval was -2.73% to +1.64%. The exact sign-flip p value was 0.875. A random two-or-four reference gave a more favorable mean reduction of 5.36%. The result did not establish an allocation gain or equal performance. We provide exact budget formulas and a condition under stable responses and independent pulse errors. We rebuilt all five voltage inputs from pinned public source files. The package preserves code, inputs, source hashes, all decisions, result tables, three figures, and reproduction instructions. This offline replay did not test an actual scout-and-return schedule or an interface outcome.

This publication supplied the exact ds004457 voltage bins, metadata, contact rules, and source retrieval and extraction code. We checked inherited hashes and rebuilt all five inputs from public MEF files. The new study tests pulse allocation.

We use its two-scout disagreement rank, site-level budget design, and exact random-allocation comparator. The new test uses ds004457 and a two-to-four budget. It adds a same-budget spread reference and the model condition for concentration to beat that reference.

- usesAn allocation from two early pulses did not establish lower maximum 20 to 500 ms SEEG mean response error at a fixed budget in eight offline sessions
This prior study supplied context for an equal-budget uniform reference and a two-pulse rank. The present study tests fixed 20 to 500 ms maps with a different maximum-site objective. The prior five-session result is not combined as new evidence.

Supplied the ds004457 voltage bins, source metadata, contact list, and retrieval, extraction, and loader code. The present analysis rebuilt the bins from hash-checked public files and retained these source selection rules.

We used its fixed recording contacts, saved contact bins and event tables, BIDS metadata, pinned source manifest, and retrieval and extraction code. We checked input archive hashes and exactly rebuilt the input arrays from public MEF files. Its response ranking results are not new results in this study.

This study informed the separate even-allocation and random-concentration references. The present study uses a different dataset and tests the score at a chosen site.
