When making these measurements if you really want an accurate answer you must take some precautions. Ideally you must check the car when it is parked in the same exact spot and also has sat for the same amount of time. Parking spaces are rarely level. Paved surfaces are usually sloped for drainage. Any differences in slope will cause the level on the stick to change. Also, the level goes up as the oil drains after shutting off the car. And with the Mercedes dipsticks that have 2.2 qts between min and max it makes it harder to take exact measurements.
