Guessing this has probably been discussed before, but I couldn’t find it in a quick search.
Why doesn’t natively automatically grade your books once it has enough information? 
If you have three books - A, B and C - and you grade C > B and B > A, why does it still ask you for the relation between C and A? Shouldn’t it just grade it as C > A automatically?
Seems like it would make grading a lot easier for people that have a lot of books of similar difficulties
