min_ticks 6 broke 5 percent striking - seven current segments where 3 gave eight, on a 36.5 s fire window against 41.4 s for eight rungs. Below the minimum the model emits min ticks every min/on periods, so the interval between pulses is min_ticks x tick / density and the base period cancels, which is also why periods 10, 20 and 40 gave identical results earlier. At 5 percent that is 2.26 ms at min 3, which struck, against 4.51 ms at 6, which did not: doubling the minimum doubles the gap as well as the pulse, and the discharge is re-struck each pulse. min 3 sits at the factory's own operating point - its 6.5 percent engrave jobs place 100 us pulses 1.54 ms apart against 1.64 ms for min 3 at that density - and 6 is outside anything the factory does. The bench is back at 3. Measured band for this tube: strikes from ~5 percent density, marks from ~10 percent at F300. That closes the pulse-structure route to a usable 1 percent, since the interval grows as 1/density and 1 percent implies an 11 ms gap. The low end is a scaling problem, and $35 is the control.
