The age slope is more than zero for all planned delay lookup rules in 122 ds000030 controls.
In 122 controls from OpenNeuro ds000030 v1.0.0, all tested shared planned-delay lookup and threshold rules produced positive ordinary least squares (OLS) age slopes for a calculated stop-signal reaction time (SSRT) score. The primary planned-delay lookup limits were 1.049966476 to 1.509403270 ms/year; adding source gender gave 0.994307182 to 1.459196683 ms/year. Allowing separate choices by delay sequence widened the limits, while an unrestricted response-time lookup recovered the negative lower limits from the source analysis. These are conditional limits for a fixed sample of 122 controls, not confidence intervals, population estimates, or evidence that age causes a change in stopping. The source does not identify delivered sound onset, and alternative timing rules, sampling variation, or model assumptions can change interpretation. No new bootstrap intervals were calculated.

Used its pinned source manifest, fixed 122-control sample, score rules, and exact numerical references. Fourteen target comparisons agree. The new analysis restricts selections to shared lookup and threshold rules. It also checks that unique response-time lookup rules recover the unrestricted limits.

Used the restriction to shared lookup input keys and its distinction from individual choices. New checks apply scanner and planned-delay keys to the fixed 166-session group comparison.
