FIG Execution judging is in 2013 as bad as ever.
Judges “box” the scores: the best are too low, the worst too high.
Judges are afraid (except on Vault) to award high E scores. The 9.8s of the past would be 8.8 or less in 2013.
Famous gymnasts and those from top nations tend to be over-scored. (Not always, as we saw with Kyla Ross in prelims, but more often than not.)
One way to separate the best from the rest would be to deduct more severely crossed legs on twisting.
It’s easy to see this error. Deducting more would dissuade gymnasts from trying to add one more half twist — at the risk of landing injuries.
