Seriously more than that, much more than that ..... but I really need to be careful how much I giveaway about the company's methods.
What's the secret. Many large companies will do takeoffs on a project like an apartment building or hotel. Many of the units are the same. So they pre-fab all the outlet and switch boxes with whips to the next. There is some wire waste but when you compare a minimum wage earner in the shop to a Journeyman the savings are real!
As to the code section cited that only pertains to an extenstion of a box by way of a Ko in the cover. I'm sure there may be a similar one in code though
