Actually the reason L6 is skippable without having to score out is that L5 to L7 is the same as Old L6 to L7. Who is to say that the skills they are using in L6 are "less than 5"? They are meeting the minimum requirements of the level. An A or B acro skill on beam... could be a BWO or a CW or a HS which are all A skills or they could do a B skill. I know some girls that think cartwheels on beam are harder than BWO and some that think handstands are harder than either a CW or a BWO.
According to USAG:
In the spirit of good sportsmanship, fairness to all athletes and competitive balance, the mobility system within the Jr. Olympic Program should be followed in the manner that it was intended:
- Before moving up a level, every athlete should show proficiency at her current level.
- Once a high level of proficiency is achieved at the athlete's current level, she should strive to move up to the next level, as long as it is done safely.
Regarding #1 - starting the season at 37+ in Level 6 shows proficiency at her current level.
Regarding #2 - 37+ would be a high level of proficiency, so they should strive to move up to L7. If the Level 6 routines are actually meeting ALL the L7 requirements, then she could safely move up to L7.
