I think when the companies estimate your time of completion for ARFs, they are estimating that you have 1 person for each task involved and they are all working at the same time to finish in the allotted time... he he he... I haven't yet finish one in the time estimated, although I am probably not as experienced as most of the people here when it comes to building so that probably is one reason. I am also a perfectionist and indecisive so I want perfect but I get stuck and can't decide on a way of doing somthing when I have more than one way to do it... I annoy myself at times.
