A fixed personal timing rule left next-day error reduction uncertain in 21 selected adults who typed 32431 and 32421

We tested a fixed personal timing rule in OpenNeuro ds006502 version 1.0.0. The score was the log interval ratio in the shared key fragment 3-2-4. Training supplied the personal score. Two untrained full sequences supplied the next-day target. Each prediction excluded the scored person from its peer references. In 21 selected adults, the fixed slope of 0.5 increased mean squared error by 9.1 percent. The mean error reduction was -0.01408, with a 95 percent person bootstrap interval from -0.16692 to 0.11436. The test left a prediction benefit uncertain. A planned trained-sequence check reduced mean error by 68.5 percent in the same adults. Short control recordings, correct-cycle selection, and unequal target precision limit comparisons. The package preserves 291 source files, the fixed plan, code, cycle records, all twelve checks, and all resampling draws. A fresh public download reproduced all 61 result files exactly.
