Social.LoadScores and huge leaderboards question

Hi all,

I'm implementing leaderboards into a game and decided to use Social unity plugin for game center and as I couldn't find a proper explanation anywhere, can someone tell me please how does the Social.LoadScores exactly work? My biggest concern is what would happen when the leaderboard gets really huge(10k+ entries), does this function actually returns all the scores in a table?
What I exactly need is the percentile of a players rank(user is better than x%) so I'd need the info on how many scores are actually in the table (IScore[].length?) and current user rank(IScore.rank).
Is there any other/better way to do that?

Any help appreciated.
Thanks

 

Ok the documentation isn't really clear here...

In fact, you have to create an ILeaderBoard instance which will be used to make queries with some options (like which LeaderBoard, from which rank, how many scores, etc)

http://docs.unity3d.com/ScriptReference/Social.CreateLeaderboard.html
http://docs.unity3d.com/ScriptReference/SocialPlatforms.Range.html

Something like :

Code (csharp):

1.  
2. leaderboard = Social.CreateLeaderboard();
3. leaderboard.id = "Leaderboard012";
4. leaderboard.range = new Range(fromValue, valueCount); // Here we go
5. leaderboard.LoadScores(result =>
6. {
7.     Debug.Log("Received " + leaderboard.scores.Length + " scores");
8.     foreach (IScore score in leaderboard.scores)
9.         Debug.Log(score);
10. });
11.
