An in-track burn separates by changing the orbital period, so displacement grows as Δx = 3·Δv·t. Lead time, not delta-v, is what buys miss distance — the same burn an hour later is worth proportionally less.

Burn is short relative to the orbital period, so the impulsive approximation used above holds.
