If you go to www.mini-iac.com and go look at the diagrams that they have available for download you will see that each maneuver is explained in detail. For instance the #2 maneuver in basic is a Humpty bump and it reads as follow

Humpty Bump; vertical up line, 1/2 inside loop over the top, 1/2 roll on the vertical down line.

So when you look at the Aresti symbols you can see that you enter the maneuver at the dot. pull straight up, establish an up line, when up high enough (your comfort level) pull up elevator to do the 1/2 inside loop. Then establish a down line and do a half roll in the middle of your down line. (down line does not have to be the same length. Just make sure that the 1/2 roll is in the middle of the down line), then pull up elevator and fly out level.

You can also go to the AMA website and download the aerobatic rules. In the back they have descriptions of most all the maneuvers and how they are done. They also tell you what will down grade the maneuver in competition.

Hope this helps.
