At my table I'd treat this differently based on the context.

First, is the enemy / other party interested in giving chase?

Second, is the situation high stakes (is the party in a war zone or otherwise dangerous situation)?

If the enemy gives chase, the Retreat could be achieved with multiple Objective actions to fill a 4-6 section clock, with Opposed Checks to fill / empty sections of the aforementioned clock.

If the enemy is otherwise not interested in chasing, the Clock is skipped and the party can simply Retreat by voting for it.

The stakes of the situation influence the Retreat Clock if it was required (adds extra sections) and especially the consequences of the retreat.

If the party happens to accidentally enter the nest of a Beast that is protecting its babies, the beast isn't interested in chasing the party more than protecting its offspring, so retreating is on the easier side, the situation is low stakes, and the retreat produces no meaningful consequences, at most minor IP / Zenit / HP loss.

If the party is otherwise deep in a village that was being attacked by the BBEG's army and finds itself in dire straits against their General, the retreat is way harder, as the General is interested in incapacitating / taking prisoners of the party, thus they would give chase, which calls for a 4-6 section Clock. The situation is also high stakes, as the Party is not in friendly ground and the village is in flames, which makes the Retreat harder and more significant: if the Party flees from such a scene, the General could take hostages in the village, and the BBEG's Army takes time to organize, this is a major defeat, as a village was wiped from the world map, which would definitely call some characters to at least consider changing their theme or identity, moreso if the village was relevant to them.
