well, you got two pictures there, but either level is fine.
Personally, I prefer to fill to the top of the hashed area. Then when I check intermittently, I can tell if it dropped.
You could just snap a photo on your phone and have that for comparison later. My "system" predates cell phones.
And the oil life monitor is bit more sophisticated than described above.
I have trusted the oil life algorithm on about 10 cars without issue.
