It kind of seems like you use a five-point system, then?

The difference being that I don't want someone to think that because I rated something 2 out of 5 that I didn't like it because it's less than 2.5. And for most people, a 3/5 doesn't mean "yes, I heartily recommend". But they can believe it for 8/10

(Actually, 7 points as someone else pointed out - by my point stands even with a 7 point system).

you use a 7 point system

I agree with a lot of your top 5 so I’ll try to continue

5: I enjoyed sections of this book but as a whole I didn’t like it

4: had some cool ideas and there were moments when I got excited but the execution wasn’t there. Basically an amateur with a good idea

3: readable but unsatisfying. I finished it but was roasting it in my head the whole time

2: garbage. Bad story idea and bad writing. Nothing good to say except that it seemed like the author was trying

1: offensive. Celebrity cash grabs, polemics, etc. no artistic value whatsoever, author was not trying to write a good book. “Book” is just a format here

The thing is, 10 means "I'm a fan" It doesn't tell anything about if I've liked it or even if I've watched it
