Also known as the 4x4 Rule.
When trying to figure out what a project will cost and how
long it will take you take the worst case scenarios that you can possibly imagine for both
time and cost. When you have those
2 numbers you then multiply them both by
4 and that will give you an accurate estimate of what the project will actually cost and how long it will actually take to complete.

Contractor: Right.
Customer: What the actual f%#k?!?!
Contractor: Hutson’s Law is scarily accurate.
