DD recently had her first L7 meet and she fell on her series bwo bwo on beam. She fell after she landed the 1st bwo. She then got up and started from the beginning of the series and did it beautifully. She scored low so I asked her coach why and she said that she received a deduction for the fall and also for repeating the bwo but that she had to repeat to get credit for the series. Why the dedection for repeating if you need it and how much is the deduction for?
