I am also of the opinion that the longer I have been inspecting, the longer it takes.
I used to do three inspections in a day, had a one page 81/2 x 11 inch, 4 part carbonless form, with check boxes and comments written in by hand and no pictures.
Now I take lots of pictures and usually include 10-20 in the report and the report is usually 20 pages or more without any boiler plate, etc.
I know more now and find more, so it takes longer to inspect and to write the report.
Oh, by the way, I charge more now, too.
I never worry about how long it takes, not one of my clients has complained about me spending too much time or effort on their inspection.
