In reality your 10 foot 2x4 is an inch or two longer than 10 feet long. Cutting a few two length isn't where the time goes since tradesmen have saws to do in in a few seconds and most boards are not cut. I did work construction - we did one house with 10 foot walls and cutting the studs to length cost a lot of time, but that was one house out of the 50 or so that I worked on
