National FIS Software : Competitors Hide Expose
As explained via the information button (the button with a question mark on it):
Competitors that are hidden are not recognized in any part of the software, This means they won't factor into any calculations or reports and can't be bought up in timing screens or edited.
Hidden competitors are stored with the race. So, if you come back to the race at a later time you may still 'expose' them.
This option is useful in a number of situations such as:
- You need to delete a competitor but there's a chance they may need to be added back into the start list.
- The race is finished and you need to do results for a specific group of competitors (hide all others). In most situations doing a report on a Block of Competitors will do what is needed but if not, try Hide.
