Jim: This is normal. Unfortunately, many RFB&D books do not have a low enough noise floor for the phrase detection algorithm to lock on to. As a result, attempting to move by sentence will move buy 1 minute or so. When you set a mark, you are marking the start of the most recent sentence, thus the problem.

I cannot use the go to book mark command to go to the place where I wanted the mark to actually be placed. Often there is a significant amount of reading before I hear the part of the book I really need to review. In other words, the mark seems to be placed somewhere in front of the place where I expect it to be placed. Any feedback? Jim King
