Dance Festivals marking

[Marina68]

Hello, my dd is dancing at Tilehurst dance festival in March. She is 8 years old and tends to do well - she is often placed in the top 3 or 4 dancers with on average between 84 and 86 marks (commended) but she has never received Distinction (87 or 88) for any of her solos whereas one of her friends who dances at the same ballet school received a mark of 88 at the last festival. Any tips on how to help her move her up 1 or 2 marks?

Also, what does the adjudicator Janet Palmer usually look for? They all seem to emphasize different things, some find arms very important whereas others look for musicality and artistry??
