Silly Wild Ass Guess

Only recently have I seen SWAG defined as "scientific" wild ass guess. That definition seems to be in direct contradiction to the point of a SWAG, where one takes a blind shot at an approximate answer to a question.
I had no idea how much was involved in the task, so I just took a swag at how long it would take.
