The car is off.
When the level is between full and low, it's easy to tell what the oil level is. There's a pretty clear line. When the oil is at least on the round part of the dipstick instead of the flat part, it's harder to tell.
After wiping off the dipstick and replacing it, I removed the dipstick again. I can see that the whole flat section is coated in oil. If I slide a paper towel down from the top to the bottom slowly, the oil starts to show up about 1 1/2" - 2" from the full mark. Some of the oil could be coming off the side of the tube the dipstick goes in. It's definitely well above full, though.
