I knew most of this. As for highlighting, I run the robowhine with the sound off, while I read the text. I read rather faster than the robowhine. However, the length of time the robowhine takes is apparently how the system calculates the amount of time it takes to read 100%. By the time the robowhine is finished, I'm typing comments. Then, I go back and pick a few sections of text already highlighted by someone else – if I agree that the highlighted section should be picked out.
