In WAG the top 8 difficult skills will be counted into the D-score. It is possible to do more difficulty but only 8 skills will count. On vault there are no maximum or minimum requirement. A difficulty has already been determined for one element. Example, Yurchenko 2/1 (5.8) or Amanar (6.3). It is fairly easy to determine the difficulty of vaults.
On bars it is pretty easy too. Basically the top 8 highest difficult elements will be counted. Bars doesn't have dance or acro (max/min) but they do have set of compositional requirements that has to be meant. Counting the top 8 skills on bars is fairly easy. Dismount element is always counted into the top 8 skill.
On BB and FX it can get more difficult to count the top 8 skills. There is a maximum of 5 aco skills that a gymnast can count and 3 minumum dance skill a gymnast can count. Dismount elements will always be counted into the top 8 difficulty. It is possible to count 4 acro and 4 dance skills or 3 acro and 5 dance skills. The rule does not always have to be 5 acro 3 dance. Often that is why there are possibilities for 3 pass routines on FX. Some jam their routines with difficult dance elements vs acrobatic elements.
Example Victoria Moors 2013 American Cup counts 4 acro & 4 dance.
Anastasia Sidorova's 2012 Russian Cup floor routine. I quite like this routine. She was originally one of the most likely gymnast to make the Russian London 2012 team. She was rumoured to have an Amanar. Unfortunately she got injured.
This beam routine is currently popular around the gymternet and I really like it. Munteanu is a very solid performer. I hope she will be successful on beam this year at worlds. Lovely leaps, difficult ff + tuck 1/1 and nice 3/1 twists dismount in connection.
