If the cost book tells me it will take 43 hours to install wood trim in a fancy conference room, and it only takes me 30, that's my windfall. It helps even out the next job when it takes us 70 hours instead of 43.

And again, as I understand it, he is using the "book" to quote repairs, then billing what he quoted. Nothing wrong with that.

but he is adding 10 to 20 % hours ON TOP OF THE BOOK TIME.
