I would agree with that Rob.
Its important though that you don't "self teach" trying to get ahead of your instructor.
All the procedural trainers need to be used in a very controlled manner to get any benfit if used in a solo manner. In fact repetion of bad habits can take considerable effort to remove.
So if you are going to use them.
Do the lesson with your instructor.
Discuss what you are going to practise and what profile.
Then practise and go no further than what you had planned.
And never used it myself but RANT really has been up there as the software of choice for procedural training for 10 plus years.
