If a job was estimated for X amount of man hours and you have 3 people working, how much could you expect the hours to be reduced. I know it would depend on the job and capabilities of each worker. But as a general rule would it take a little more than 1/3 to do the job with 3 vs 1?
What about 2 vs 1, a little more than 1/2 the amount?
