I was looking through lap times of different production cars, and there are some wildly out of place cars doing ring laptimes, some cars are faster than they seem they should be, while others are slower than they should be. Which got me thinking how some cars truly get tested in showroom condition, and others get the “marketing” treatment to produce a laptime a showroom car would never touch, solely to sell more cars. Then I found this article that talks exactly about just that.

And not only that, different cars are going to have different gaps between pro and normal drivers based on their nature.
Its a slightly to moderately interesting metric but anybody who considers it a factor in their purchase decision is a dope. Anything the ring time tells you could should have already been figured out elsewhere.
