Ok, so i suppose you've seen an inspector that actually opens an outlet or
junction box??? I think not. And besides, the tape is perfectly acceptable
procedure.

dittos on that. Just finaled a project. The inspector inspected the panel
when you could see the wiring. In other inspections, the wire was inside
the boxes, first without nuts, second with nuts after trimming, and on the
final, just pushed the button on the smoke alarm. I figured by that
inspection, he had seen enough previously to lead him to believe everything
was right.
I would say that IF an inspector pulled a plate, that it was from something
he had seen on a previous inspection that said, "Check this work again
before final!" Ours was a nice guy, even when things weren't quite right.
He'd just tell us how he wanted it, and check it on the next inspection. It
was always done, and voila!
Final passed.
woohoo

I most certainly have. In fact, in my last inspection, the inspector
noticed that the electrician forget to grease the aluminum subpanel feed
connection in the subpanel (which required pulling two panel covers off
to find out).
He was about to slice apart the tape and U-bolt splice at the other
end's junction box before I told him that I was standing talking to the
electrician when he greased it, "I didn't see him do the other end,
but yes, I guarantee you he did grease _this_ end, and I'd rather
not have to redo _these_ connections.".
> And besides, the tape is perfectly acceptable procedure.
Of course it's acceptable procedure. But if the inspector has
reason to believe that you've been cutting corners elsewhere,
the tape may be a red flag, and he may open up at least one
to see if you're hiding. If he finds a sloppy connection, he may
well start opening more.
At that, the wording I was using is partially paraphrased from P.S. Knight's
books on electrical wiring (which are the DIYers bible for wiring
in Canada. He also writes/publishes the primary training material for
Canadian electricians) on _exactly_ this topic (taping wirenut
connections).
See the electrical wiring FAQ on the same topic.
Of course, some inspectors don't do much. Others take things rather
more seriously. And apparently some don't do much if you install a
bottle of scotch in the main panel. I liked having this inspector out -
not only did he find what might have caused serious problems later on,
he also gave me some valuable advice for the wiring of the garage
itself, and saved me a lots of work and money when it was done.

You've described the process done incorrectly. Practice on some scrap wire
until you get it right.

I twist it, then clip it to the proper length, then screw on the nut,
works every time.
If I am pigtailing a real lot of wires (over 4) then I'll twist it,
put on a wire tie (at end of insulation), clip it to length, then
screw it. The wire tie prevents the twist from falling apart while
you clip it and get the nut on.
