Yeh thats the whole point of revving it for 10 seconds.. If the needle is already in the middle, most people dont appear to be revving before shutoff..

Oh, now I get it [thanks to others]. You meant to ask "If the coolant temperature needle is at the midpoint of its range do you need to follow the Rev procedure?"
The answer is No, since the vehicle is already warmed up.
If however the coolant temp. needle indicates below nominal operating temperature (to the left of midpoint) then Yes the procedure is recommended.
You'll find that using fully descriptive sentences, especially when posing a technical question, makes life far easier for others and you'll get better and more timely answers.

Like...idling your car for 2 minutes before you turn it OFF after a long drive/use...thinking you are "cooling" it down when in fact you are only heating it up more!

NO. Last time I did that I flooded my 8. And it was not a short drive and it was not cold. I let the car warm up. Did a 20min run then reved up to 4k rpms and shut if off. Next day car would not start. Geeez. Stupid *** at the dealer told me I drove it for a short distance lol what ever. Lesson learned.

Who said anything about reving when the engine is warm? From what I have read the problem is when you drive a short distance and then shut it off cold. The engine runs rich the first few minutes which is probably the reason it will flood. If you rev it up warm you are just making it run rich again.... The solution to this problem IMO is to simply let your car warm up and cool down if you have to say, move it out of the driveway. Sometimes I let it run for 5 minutes and then go back out and turn it off (this method doesn't work if you live in a rough neighborhood). I think some people here are mistaking basic rotary maintenance for having a turbo. If this was theway to go then everyone here would buy a turbo timer for n/a 8's..... stupid.

Momentum Keeps Me Going
The only thing reving the engine before turnoff does is, as soon as you turn the key off, fill the combustion chambes with unburnt gas at a higher rate than idling would. And as the ignition is off and with no spark, the unburnt fuel (gas) collects and washes the rotor housing walls, providing ample opportunity for flooding the next time the car is started.

My 8 never moves until the temp gauge is pointing north and the car has been running for about 20 minutes (give or take). No need for a rev.
I also hate having to move the car for others then waiting for it to warm just to shut it off again.
