The important thing is the dipstick shows the correct amount when the car is sitting on it's wheels on flat ground.

Same with engine oil. I usually drain a little more than normal, because I rotate my tires while it's draining. Lifting up each corner around the car drains out a little more of the dirty oil, which I think is a good thing. Trust the dipstick when it's all done.
