I usually give a range of estimation.

The issue I've had is that most "stakeholders" just want it boiled down to one number and don't care about any nuance. If I say it will take 2-4 weeks, they will assume 2 weeks if it's convenient. If there's a list of tasks, they will add up the lower bound of each task and discard anything they don't deem necessary.

It seems to me that any estimation tactic works well if you assume fair intent.
