I don't see any harm for you to take 1/2 quart at a time out until you get to the right level.. then sleep easier

I'm curious to know what professional recommends this course of action or if this is simply internet lore that has become fact...
IMO, this practice is a bandaid for a different problem. I don't know of one high level shop that purposely fills a customer's car with oil to only the middle of the dipstick during an oil service and we certainly didn't perform this practice at Andial, regardless of engine size or whether it was turbocharged or normally aspirated. Can one of the professionals here (Steve Weiner, John Walker, Henry Schmidt, etc) confirm that this is accepted practice?
I have my personal car's oil level just a tad under the top mark on the dipstick when at idle, on level ground, and at operating temperature and I have NEVER had a problem with oil blowing through the intake system as described above. I'm also fortunate that the motor doesn't use any oil so I never have to refill before the 3,000 mile drain interval I use.
