For the basketball throw watch the You Tube videos and read about techniques. My DS added 20 ft after watching the vidoes, reading about technique, and practice, practice, practice. I told DS to think of the BB throw more in terms of a discus throw and less of a football forward pass. You can also find lots of info on CFA maximums and averages, but each SA has its own minimums. Also practice, practice, practice all the events. It also helps to simulate the CFA or parts of the CFA. A one mile run, push-ups, or sit-ups may be easy alone, but not as easy after all the other events. Consider doing 2 or 3 events in a row under CFA time limits.
Good luck.
