Talk:Trial Event

My understanding of this page is that the "Years Run (Nationally)" section in the table is used to indicate that former trial events were run as official events on the national level (see: Code Busters or Hovercraft). If that's the case, should events such as Hydrogeology and Roller Coaster be added to the table in order to show that they were formerly trial events? If these events are added to this page then should they also have the Trial Event Pages category, or is that just for events that have never been run officially on the national level? --Jaspattack (talk) 22:56, 11 January 2019 (UTC)
