I think that summary of a sportsman flight is pretty biased. Its like 3 sets of a few basic elements. At that level pilots are not perfectly setting up their out of box turn arounds, and if they are its probably with a banked 180 turn.

If two loops is hard for you, spent an entire day practicing. And add in your 1/2 Rev Cuban for turn arounds. Practicing 2 moves, not too tough. Next day, try 2 different moves. Every day you fly, pic 2-3 moves to practice. When you are comfortable, try linking a few together.

It is amazing how fast you progress, you just have to start.
