The progress bar shows how far you are from reaching the next goal. This can be the depth to win a variation. As soon as this has been achieved the progress bar shows the time needed to win the next variation.
When there is nothing left to win the depth goals for a position have been reached and the message “Deep Analysis” appears in the Chat window of the Live Book window.
