- Spearchucker 9y agoWell, they would be, being estimates. If they were right they'd be facts. The problem with estimation is that people view estimates as fact, when (according to Steve McConnell) all estimates should come with a variance of + or - 4. I like to present my estimates using the cone of uncertainty, which demonstrates their fallibility well. https://en.wikipedia.org/wiki/Cone_of_Uncertainty https://en.wikipedia.org/wiki/Cone_of_Uncertainty
