Oh, wow. Usually I get asked to estimate with very vague descriptions of what I am going to build, with hard pressure on date of delivery. At one point I said to a manager that if he pushes hard enough he will get any estimate he wants. Well, for the scientifically inclined, humans can estimate programming tasks that take around one hour with good precision. Precision declines until one week and anything over a month is virtually impossible to estimate.
