scoring system As know AMA scaring uses simple 10-40 point score maneuvers multi ple-camponent maneuvers ie Three Consecu tive Inside Loops being given score FAT utilizes 1-10 scale individual compo nent consecutive maneuvers multiplied its own difficulty K factor total scare maneuver thus sum segments score multiplied its separate K-factor added together Given difficulty finding competent judg es under best conditions feel penalize ourselves insisting employ judging system have never used before likely will never use again opponents such procedure will cor rectly point out FAT system puts special emphasis difficult maneuvers via difficulty factor whereas AMA system ranks maneuvers equally should therefore select team using same system under will flying World Champs could result
