What, you mean the manual is not for the meek?
I thought it was over simplified.
The map overlay feature you can test on your laptop. Just pull up any map (google) and press the "Prn Scrn" button and then goto MoBo and press the "Insert" button.
My recommendation for advancement would be:
1) Simple Intercepts
2) Using the Map Scale Tool
3) TSD tool to determine speed
4) 20k Lead Intercepts
(Anything beyond this is advanced)
5) Two-legged attack stationing
6) Chapter 11 US Navy OpSpec problems
7) Stationary TMA w/speed guess
8) Stationary TMA w/triangulation
9) Moving TMA
