I feel obligated to remind everyone how to actually estimate estimations given by developers

Take the number your developer gives you, multiply it by π (≈ 3.14), and mark that as the real delivery date.

Because a developer’s “straight-line” path from A to B is imaginary. In reality, we wander down self-made rabbit holes—tinkering, over-engineering, and discovering “critical” issues nobody asked for—so the straight line becomes an arc roughly π times longer. Multiplying every estimate by 3.14 simply corrects for that built-in detour.
