The delay difference is 50 ms in 160 balanced ds000030 staircases with no floor clipping.
The scheduled STOP delay difference was exactly 50 ms in 160 of 532 ds000030 staircases that had equal numbers of responses and nonresponses and no floor clipping. For the 50 ms update rule, an exact identity expresses the difference as a step term, an endpoint term, and a count imbalance term. Rational arithmetic gave zero residuals for all 530 defined staircase differences and all 265 defined run differences; a second implementation agreed. In the 241 runs selected by the inherited screen, the mean scheduled difference was 51.957218799226 ms. This is a descriptive result conditional on the task update and selection rule. It does not estimate a biological stopping time, establish a causal effect, measure tone onset, or establish population generality.

[Legacy relation: reproduces] New local code agrees with all 266 primary selection flags and all 265 defined scheduled, recorded, and zero-replaced delay differences, with absolute error at most 1e-9 ms. This relation covers those point calculations and the primary means only. It does not cover bootstrap intervals, rank probabilities, independent source retrieval, or biological validity.

Its equivalent endpoint identity and balanced-sequence checks motivated the centered-cross-product decomposition and the independent-response reference. I claim no new endpoint identity and executed no downloaded code.
