Wire Length and Code From Box Edge to Device

I'm writing in hopes of relaxing my perspective about wire length to devices. But first, if I understand code:

--you need a minimum of 6" wire length from point of wire entry into device box TO wire end outside the box.

--a minimum of 3" wire outside the edge of the box.
--neither rule above supersedes the other.

That being said I commonly see 8, 9, 10 inches, even a foot of wire outside the box. This seems excessive to me, as in the attached pic...9 + inches outside the box on two 14-2 cables...and this was stuffed in a single gang handy box with an outlet. Yikes!

(The box surface protruding is another story...the box was put on concrete block, probably first, before the wall guy goofed over it.)

As you already stated the measurements in the code are minimums. There is nothing wrong with having more wire than the code requires. As long as it fits in the box you are good to go.

Well yes nothing wrong per se, but it's just feels annoying, and seems rather needless to stuff that much extra in a box.

That's called a utility or handy box. It's screwed to wall from the back.

It's rare to see too much wire. Usually it's too short. Easy enough to cut shorter.
