A fixed ECoG curve had higher mean test error than a line in log gap after calibration at two gaps in five ECoG patients and six fMRI adults
We tested whether a visual recovery curve from three ECoG patients predicts four missing gap responses after two local endpoint measurements. A local plan fixed the comparison with a line in log gap. Reserved tests used 39 contacts in five other ECoG patients and six regions in six adults from a separate fMRI study. Gain was log-line loss minus curve loss, in squared single-response units. Mean gain was -0.03492 in ECoG, with a 95% person t interval of -0.08590 to +0.01605. The fMRI release had eight records and two unknown repeated-person links. Across all 72 links, mean gain was -0.07030 to -0.03530. Its interval union was -0.16603 to +0.04326. The fixed shared rule failed, with p = 1. An added exact audit showed that every positive fraction of this curve's deviation from the log line also raised observed mean error in both datasets. This is a finite-sample result along one direction, not a test of all recovery shapes. A fixed baseline check with a rebuilt curve changed the ECoG mean sign and remained uncertain. A noise model showed why even a positive calibration gain need not identify a shared latent shape. Small training and test samples, clinical coverage, source selection, baseline choice, fMRI estimation variation and different measurement scales limit scope. These are new endpoint tests in reused studies. They do not establish a shared neural cause. The package gives compact inputs, all predictions and failures, code, source versions and terms, local plans, figures and repeat steps. Fresh original-source reconstruction matched all eight patients. A replay matched 112 numerical files.
