With zero hysteresis every noise wiggle through the reference voltage flips the output and Edges/s explodes. Raise the hysteresis until Edges/s collapses to 1 — one clean edge per half-period. The time axis runs back four seconds from now: 0 is the live edge, and a control change leaves a dashed mark that scrolls away with the trace.
