The organization of a competition can decide whether or not registrants may enter their personal best performance. The organization can also set the period in which a personal best performance must have been achieved.
The organization can also indicate the source of the best performance. They can choose whether it is exclusively performances recognized by the Dutch Athletics Federation or the Flemish Athletics League, or whether it can be any performance included in the athlete profile of Athletics.app.
This means that it is possible that an achievement is visible in your athlete profile, but that it does not meet the requirements set by the organization, as a result of which a best performance is not automatically entered.
