使以前只求动作完美的体操比赛不得不增加难度才能得高分，逼运动员冒更多的险。

For over 80 years, gymnastics was based on a point scale that ranged from one to ten. However in the 1990s the rules were adjusted and each routine was given a start value based on its level of difficulty, making the infamous “perfect ten” more difficult to achieve. Then in 2005, the rules changed once again due to a scoring controversy in the 2004 Olympic Games. (For more details about the controversy, see iSport.com’s History of Gymnastics)
After the 2004 Olympic debacle, the FIG scrapped the old one to ten scoring range for a new, more complicated judging procedure. The new scoring methods include an evaluation of both the difficulty of the routine and the execution.
The degree of difficulty is decided by the skills performed by the gymnast. Each routine starts at a difficulty of zero. Points are then added for each skill, which can range from A (easy) to F (very difficult). (For example, a back handspring is considered an easy skill and is given a value of A that is worth one tenth of a point.) Each level (A through F) increases by one tenth. Required elements add a maximum of 2.5 points to the score with bonus points given if difficult elements are strung together in a routine.
Most elite gymnasts have a difficulty ranging from the high six’s to the low sevens.
Two panels of judges are present during competition: Two “A” panel judges that determine the technical difficulty and six “B” panel judges that judge the execution and artistry of the routine. The execution score starts at 10 and points are deducted with each error. (For example a fall off the balance beam results in a 1.0 point deduction.)
The difficulty and execution points are added together to give a combined score. A good score in this new system is around the mid to high 16 point range.
