If you want to randomize in an advanced sequence so the user does not memorize the pattern each time the drill is executed, you can do so with the 'Random Start, Random Step' option. You can mix up the steps, so it is randomized whenever you start the program with this feature. It is available before you will run the sequence.
Random Start: Starts sequence in a random spot (i.e., Step 3) and then continues on sequentially.
Random Step: Starts sequence at a random step (i.e., Step 3), and then randomizes the next steps also (i.e., Step 5, Step 1, Step 6).
Turn one or both to "ON" to activate this feature.
