The Code of Points, Article 9.2.17 states the following:
Landing with feet slightly apart and gymnast lifts heels and joins both heels together without lifting and moving the front of his feet – No deduction
There have always been discussion surrounding what is meant by “slightly”. …
If the feet are more than 10cm apart there will be a 0.1 or 0.3 deduction taken, even if the heels are brought together after the initial landing. (Article 9.4)
