How do you eliminate reverse sensing during a back course approach?

What is the process to track outbound on an NDB bearing?
To determine the heading to intercept this course, you would first fly parallel to the bearing course, then you would note the difference between the tail of the aircraft and the pointer. Let's say the difference was 30 degrees. You would multiply 30 by 2, then fly 60 degrees towards the bearing. Once the ADF pointer change 60 degrees after your turn you would then turn 60 degrees in the opposite direction from the first turn. Now you are tracking outbound on the desired bearing.
