A point to consider is that many of your inspectors have been involved in first far longer than you have, and the rules over the years have changed, however from year to year the changes are usually very small, and some have been long standing rules, such as the tape rule that has been in the manual since 2000 (when I started) and it was taken to be a given. Usually it is these rules that stand out, the changed rules that we must really study, and as said before, subtract from our mental list. Think of it this way, the speed limit near your home has probably been the same your whole life, if it were to change and you saw the sign about the change you would obey it, however if you 2 days later were just running down the street to a friends house it would be second nature for you to go the old speed limit, until you trained yourself not to. Think of the problem you sometimes have in math when you are subtracting a negative number and end up actually subtracting, and not adding, its a small mistake that is very common.
P.S. if you have something mounted or secured with duct tape, don't you think you could have done done it a little "better" ?
