Yes that is exactly what I was doing while back-counting. A back-counter needs a cover to hide himself in order to not get any attention of the pit or the eyes-on-the sky. I was trying to look like that I was interested in the other games next to the table i back counted. I also played some other games. However, after a certain period of time, no matter what you get attention because people get to see you around the tables periodically.
