The capture reached the title AFTER the harness stopped classifying, so the plate's ramp was in the log with tick stamps after all. ptbtn00: alpha 11->231 over 334.4 guest ms = 657.9 alpha/s. With its independently attested T=22 that is 56.8 units per guest second, inside the pre-registered 55-65 band. The final step of every ramp is excluded because it clamps at 255 and reports more elapsed time than it consumed -- including it drags the plate to 633.0 alpha/s, a 4% error entirely inside the clamp. Control passes at 1.15%: ptcopyright gives 650.4 alpha/s, and at one shared clock that makes its own segment T=22.25. Two elements agreeing on a rate AND independently landing on a round declared length is stronger than either. Why my earlier 29.9 was wrong, and it is the failure the page predicted: it used T=15 borrowed from a row that is about A element with a 15-unit fade, generalised to splash B's quads, which is not what that row says. At 56.8 the splash elements' implied T is 23-34, none of them 15. And the step quantum does not rescue 15: splash steps are multiples of 17 = 255/15, which is what made 15 look confirmed, but at T=28.5 a step of 17 is simply TWO units of 8.9. A quantum fixes T only if you already know the step is one unit. 60 is NOT refuted -- 5.6% away against ~5% quantisation resolution -- so the port keeps it. But this DOES eliminate the unit constant as a cause of a late plate: at 56.8 units/s t=236 lands at 4.15 s against the port's 3.93 s, so the port is fractionally early.
