Only rated players add to the value of an event. In the first 5 registered events the player is not “Rated”.
When the player becomes Rated, the experience they now have triggers them to begin adding value to the event based on that skill and experience that has been shown.
We don’t go back in time and pretend that player was an “experienced” player at their first event. The value calculation for every single event is based on the data available at that specific point in time.
This goes for not only whether a player is Rated or not, but if someone was ranked 1000th 3 events ago and is now ranked 89th, the value they brought to the tournament 3 events ago doesn’t get re-graded based on that future activity that eventually took place.
