Members have two methods of comparing their skills against other members. The first is the rank, which is a measure of their balance of wins and losses. The second is their rating, which is similar, but takes into account the skill of their opponents in assigning a value to the win or the loss. Players slowly advance through the ranks to reach the pinnacle which is a 4-star general. They also rise through the ratings to be listed on the Top 30 List.
Players rise in rank according to their success on the battlefield. Ranks are attained either by achieving a minimum number of RANKING POINTS or by reaching cumulative games played requirements. In addition to win/loss requirements, officers must successfully defeat players of appropriate rank to advance. Finally, officers must maintain a certain minimum number of RATING POINTS to reach and maintain any given rank. Players who fail to maintain the minimum requirements of their rank will be demoted as soon as this occurs.
CHALLENGE GAMES
Officer candidates (players eligible for officer promotion once they meet officers defeated requirements) may challenge officers to achieve their promotion. Officers are expected to accept at least one promotion challenge game every six months.
STANDINGS
Standings (ratings and rankings) will be emailed to the membership weekly. The website will maintain current rankings and ratings as game finishes are reported to the site.
In the rating system outlined below, please remember the distinction between ratings points and ranking points. RATINGS points are a numerical representation of the strength of the player. They are gained and lost in relation to the strength of the opponent. RANKINGS points are a value of points accumulated in play that represent the win/loss ratio of the player. It also takes into account the type of games played, as some games have traditionally been given special values in the past.
Convention games
code W
A convention win is worth 4 Ranking points
A convention loss is
worth 1 Ranking point
Normal Games code #
A win is worth 1 Ranking points
A loss is worth 2 Ranking points
Live games code L
A win is worth 2 Ranking
points
A loss is worth 2 Ranking points
GMless games code G
A win
is worth 2 Ranking points
A loss is worth 2 Ranking points
Face to Face
games code F ( still unused until local chapters begin )
A win is worth 2
Ranking points
A loss is worth 2 Ranking points
Tournament games code
T
A win is worth 1 Ranking points
A loss is worth 1 Ranking point
Submitting a game log will get the winner an additional 1 ranking point
Formula for calculating the RATINGS POINTS is below:
When a game is started;
First a differential (D) needs to be obtained for the game:
D=SUM(P1atStart-P2atStart)/10
Then a value (V) must be assigned to the game:
IF P1 wins the game: (P1V)
AND
IF SUM(15-D)<2
THEN V=2
ELSE IF SUM(15-D)>20
THEN V=20
ELSE V = SUM(15-D)
IF P2 wins the game: (P2V)
AND
IF SUM(15+D)<2
THEN V=2
ELSE IF SUM(15+D)>20
THEN V=20
ELSE V = SUM(15+D)
The above values will be automatically inserted into the game db for that contest.
When a games ends;
First the current ratings of the two players needs to be looked up:
Then the server will determine if P1 or P2 won the game:
Apply the game value as follows:
IF P1 = Winner
THEN P1 current rating
+ P1V = new P1 current rating
AND
THEN P2 current rating - P1V = new P2
current rating
If P2 = Winner
THEN P1 current rating - P2V = new P1 current
rating
AND
THEN P2 current rating + P2V = new P2 current rating
The winner would gain the appropriate number of RANKING POINTS as determined by the game type (Normal,Tourney,Convention,GMless,Live,Face to Face) and the Loser would lose the appropriate number of RANKING POINTS.
Then the AACRS ranking routine for those 2 players will then be recalculated with the below guidelines:
Officers
**** General - 1400+ RATING POINTS AND 4 or more General vs General wins than losses AND (44+ RANKING POINTS OR 70+ completed games)
*** General - 1375+ RATING POINTS AND 3 or more General vs General wins than losses AND (40+ RANKING POINTS OR 65+ completed games)
** General - 1350+ RATING POINTS AND 2 or more General vs General wins than losses AND (36+ RANKING POINTS OR 60+ completed games)
*General - 1325+ RATING POINTS AND (Win vs COL+ AND 2 other Officers) AND (32+ RANKING POINTS OR 55+ completed games)
Colonel - 1300+ RATING POINTS AND (Win vs MAJ+ AND 1 other Officer) AND (28+ RANKING POINTS OR 50+ completed games)
Major - 1275+ RATING POINTS AND (Win vs CPT+) AND (24+ RANKING POINTS OR 45+ completed games)
Captain - 1250+ RATING POINTS AND (20+ RANKING POINTS OR 40+ completed games)
Lieutenant - 1225+ RATING POINTS AND (16+ RANKING POINTS OR 35+ completed games)
+++++ Enlisted +++++
Master Sergeant -- 12+ RANKING POINTS or 30+ completed games
