Several possibilities come to mind:
1. Based on how long the book is actually open in the reader.
2. The last page reached in the book.
3. The book being marked as completed, regardless of how long the book was actually open in the reader. I am hoping this is the actual situation.
None of these may be correct so I would appreciate the actual correct algorithm used by Amazon in determining the royalties. Thanks in advance for your help.

Kindle Unlimited is a loan not a purchase program so quite a few people will pick up a book, read a few pages and then DNF the book so paying a royalty based on the loan would not be fair to authors whose books are being read.
The closest to reality would be your #2 with quite a few other constraints. As near as I can tell, the algorithm pays based on the read page counts. There is a limit on how short a time the average time to read a page can be to keep robots from flipping pages as fast as possible. From reports from one source, it appears that reading each page in the same time is also considering a sign of a robot being used. The page counts are based on the word count based on ~200 word per page (Kindle Edition Normalize Page Count KENPC). This was done to combat authors who were using very wide margins and large line heights to generate more pages from the same number of words. From reports I've seen by authors, the payment per page read has been dropping for a while now to the point where some authors are leaving KDP and going wide. One item I read indicated that a book that used to earn $1.25 when fully read in KU is now earning about $0.78 so an ~38% drop in income.
#1? Nope. Kobo uses time reading for the Kobo Plus program. Something which hurts authors that I read since I have a fairly high reading speed so don't spend as much time reading a book.
#3? What would keep someone from downloading the book, going to the last page and then closing the book? That was often stated as the reason you saw a lot of books with the Table of Contents at the end so that the author was paid the full amount when the ToC was used. Which might be why Amazon closed that hole.
As for the actual correct algorithm? Good luck with that. Amazon gives out as little information as possible precisely to make gaming the system difficult. Some people have done experiments which seem to indicate it is a fairly complex system with multiple criteria to limit the effects of robot farms.
