"During a calendar year, only one National Senior Championships per each Member Federation can award Placing Scores according to the Categorisation as shown below. In case a Member Federation organizes more than one National Championships, or an equivalent type of competition (e.g. trials), in any discipline within one calendar year, the first such competition is regarded as the National Championships unless the MF informs World Athletics otherwise, prior to the beginning of the season."
So, National Championships count only one time, right? I'm having doubts with this one.
