I think the estimates completely random are unreal, think of a real case to go to engineer and ask him "do you think it costs a piece with these characteristics?" and he says "approximately $ 1,000" back on 5 minutes later and was like "approximately $ 1,800". It is unrealistic, in my estimation should be deterministic and the rounded figure depending on the skill of the engineer. If the piece costs $ 566.23 a good one will tell you "costs approximately $ 570" maybe one less good "aprossitativamente $ 600" but still the same amount unless you change the characteristics or the engineer.
