How much oil should be on my dipstick?

The next day, when I start the car from cold, the dash gauge shows one bar overfilled.

And by the way, I am wary of the horror stories of overfilling with oil. Check the oil level with the motor running and the oil will not even register on the dipstick. No way the crakshaft is going to aerate the oil. Obviously, if you overfill by 2 quarts you may have a problem, but when I go to the track, my major concern is oil starvation from from hard corners. I'll risk a puff of smoke from an overwhelmed aos over a spun bearing any day.

wouldn't a deeper sump mod mitigate oil starvation while removing the possibility of losing the engine due to a downed AOS from overfill?
