Hello and welcome to the URPG Ladder.
What is the URPG Ladder?
The URPG Ladder is a system that scores players and ranks them in a leaderboard.
The purpose of the URPG Ladder is to promote activity and competition. It also aims to give an accurate recording of where players stand in skill in relation to others.
What do I get for participating?
There are no current official rewards for doing well in the URPG Ladder; however, officials and/pr moderators are free to implement prizes if they deem it fitting. It is not reccomended they do so yet, as the URPG Ladder is still in its pioneering stage. Unofficial rewards include bragging rights and the admiration/hatred of others.
Who can participate?
Anyone part of the URPG that is capable of fulfilling the three Pokemon requirement in the standard URPG Ladder rules.
How do I participate in a single battle for the URPG Ladder?
First a referee is required to none other than ref the battle. Then, for a standard match of one person against another. Players may ask one another for a Ladder Match on the Forum or AIM. Once the battle is done, the referee must post the battle log. The referee should include in their battle log that the battle was a ladder match. Then, any one of the two battlers, or the referee must post in this thread and link to the battle log to acknowledge the completion of the battle. Once this is done, the participants must merely wait for the results to be processed. Players can continue to participate even if the latest battles have not been processed, but players should be wary that the leaderboard in this post may not be up to date.
What are the official rules for a single battle for the URPG Ladder?
3 VS. 3 or 6 VS. 6
No Use Items
No Hold Items (Can be used if BOTH battlers agree)
These rules are flexible and may change.
How are the rankings calculated?
The URPG Ladder uses the TrueSkill system developed by Microsoft:
Each player is given a µ (mu) and σ (sigma) rating. µ denotes a player's average skill and s denotes the uncertainity of that skill, the range of which your true skill can actually be. Participants in this ladder will start with 3000 µ and 1000 σ. Updating the µ and s of each player after a battle will be done by using this calculator:
Your position of the ladder will be based on who has the higher conservative skill estimate, µ - k*σ. The constant k that will be used will be 3. The result will be rounded to three decimals.
To learn more about the rating system, including how the µ and σ update for each player, be sure to read the original hyperlink given.
You will be added to the Leaderboard once you've completed your first battle.
