the reading stats idea is fatally flawed.
1. if you start a new book & flip thru many opening pages of pointless bumff - title pages, dedications, epigrams, praise.... in order to get to the actual story. that is all used in your reading speed. so you are now assumed to be able to read a page per second!
2. if you actually remove a part-read book, then re-add it & start back in the middle, the algo has no idea what's going on and cannot estimate how many hours to completion.
3. again, on the how long left - you may not be planning to read each and every one of those 150+ pages of footnotes at the end of your mega-tome, but the devicxe does not know that
