I have a 9 year old that just completed L4. She was also having trouble with the vault. She usually scores around 9.5 or so in everything else and the the vault was ruining her AA chances. I thought that possibly something might not be clicking with how her coach would explain things for the vault. I know as a teacher sometimes it doesn't click with certain students and that someone else can explain it to them better. I checked with her coach to make sure it was okay and then asked the boy's coach for some 30 minute privates. The first 3 meets were 8.25, 8.45, 8.45 and then after the first private 8.7, 2nd private 9.05, 3rd private 9.15. It could be that she was just improving over time, but the boy's coach had her do some things that she hadn't been doing previously. So, what I'm getting at is maybe a new technique or a different perspective helps.
