"Wins" in ResultMaps have the same security as any item, objective, value or individual who has been linked to the win.
For example, if your win is for a personal item, only you will see it.
If you tag someone else in the win, that person can see it and it shows up in their scores.
If you tag a shared value, then the people who have rights to the value can see it.
If you log completion of a shared item as win, everyone who can see that item will see that was given a “win”
