My discord book club gives points for pages read, so I have a good idea of how many pages I read in a timeframe.

And most of my reads are KU, so I'm able to go back through them to remind myself if I read something or not. I'm too lazy to get a Goodreads account, so sometimes I'll pull a sequel to a book I don't remember DNRing, but I'll remember a few pages in. Wish I could get Amazon to quit recommending books I already read, or that I read and didn't like.
