The first year of L5, our team didn't have any. This past year, we had 5 girls compete L5. They are all moving on to L6. I am betting all of their AA scores will go up (31.0 - 32.7 high scores), even if their bar scores stay about the same.
BUT, I can say that we had a girl score out of Old L6 so she wouldn't have to compete L5 that first year. In Old L5, her season high score was a 34.0. She scored out of Old L6 with barely a 31.0. Her first year of New L6, she had a season high of 33.7 (bars killed her... 7.9 high score). This season, she repeated L6 and her season high was 34.275 (bars are up to an 8.3 high score).
