Week 3 Recap

The action in the NCRHA picked up over the weekend with three regions (SECRHL, ECRHA and SCHL) starting their respective seasons. The opening weekend wasn't without its share of upsets or newcomers to the TOP 15 poll.

In Division I, the University of Florida came out as expected and posted a 3-0-1 record to maintain their 4th place ranking. The only movement out of the poll was Florida International, who finished the weekend with a 1-2-1 record. Cal Poly SLO moved into the poll for the first time this season and takes the 15th and final spot in the poll. Lindenwood University continued its national record of 22 consecutive weeks being ranked 1st in the country.

Division II was subject to a ton of movement after a upset filled day. The University of Miami struggled out of the gate, dropping out of the rankings are a 2-1-1 weekend. Joining Miami on the way out was 5-time defending SCHL champions, the University of Texas-Dallas. UTD failed to win a game, going 0-1-2 on the weekend to fall out of the rankings. Stephen F. Austin State University joined the rankings after starting the season with a 2-0-1 weekend in the SCHL. Slippery Rock University also joined the rankings after going 3-0-0 last weekend.

Division III remained pretty much the same, with just some minor leap frogging going on. St. Charles, the defending National Champs, moved into the top spot for the first time this season.

Look for the IRC B National Rankings in just under two weeks. Additionally, anyone who would like to submit game pictures for the column on the right hand side of the page is asked to e-mail IndRankCom@gmail.com and we will do our best to get them onto the site.

Oi, achei seu blog pelo google está bem interessante gostei desse post. Gostaria de falar sobre o CresceNet. O CresceNet é um provedor de internet discada que remunera seus usuários pelo tempo conectado. Exatamente isso que você leu, estão pagando para você conectar. O provedor paga 20 centavos por hora de conexão discada com ligação local para mais de 2100 cidades do Brasil.

(If he will be possible add the CresceNet(www.provedorcrescenet.com) in your blogroll I thankful, bye friend).

The Rankings Explained

Since the conclusion of the season both founders set out to find the best solution to answer the age old question, “Who’s #1?” After much search, the answer was to use a mathematical formula to calculate the answer. Removing the human element from the voting would likely result in less biased rankings towards individual teams and regions.

The solution would be found in the ELO chess rating system. They system was created to rank chess players by another means that wins, losses and draws. The system uses a mathematical formula to reward each person for impressive feats and punish them for lesser impressive feats. Because chess and inline hockey are two different animals, the general equation had to be changed to allow for more hockeys related factors into the equation.

Using the FIFA Women’s World Rankings as a guideline (Elo Based), we managed to change the rankings to suit the nature of our sport. The rankings include the importance of the game, the outcome of the game, the expected result of the game, and the goal differential of the game when calculating a result. To better explain the way the rankings work I give you the following examples (all team start with a ranking of 1500):

Lindenwood University (1500) vs. UMSL (1500): If Lindenwood won the regular season game 4-3; they would be awarded 15 points for the victory and UMSL would be docked 15 points. However, if the game was won 12-2, Lindenwood would earn 39.38 points for the victory and UMSL would be docked 39.38 points. Additionally, the importance of the game could change, using the national title game as the example, with both teams having equal ratings Lindenwood would be awarded 52.5 points for a 6-3 win.

However, as you could assume, two teams having the same rating would be rare. Each teams point total carries over from one week to the next and from one season to the next. The following is a example of two teams with different point values and the different results it can produce.

Lindenwood University (1746.38) vs. Illinois State (1360.88): There are a few things that you can determine because of the vast difference in each teams rating (385.5). The first is that Lindenwood is expected to win the game. The second is that Illinois State winning the game would be a much bigger accomplishment that Lindenwood winning the game. The maximum points Lindenwood can earn from this game is 7.72, which would mean they won by at least 10 goals. However, on the flip side, if Illinois State was to win the game by at least 10 goals they could earn as many as 71.03 points. This is based on the projection that Lindenwood would win the match-up 90% of the time.

As the two examples show, there are a bunch of positives when using this system. For starters, once a team has achieved a high rating, it becomes difficult for them to increase it without playing a higher level of competition. This rewards regions that have more competitive teams. It also rewards teams who travel out of the region and win games against other higher rated teams. For example, last season, Towson and Army both played James Madison who would have had a higher rating that both visiting teams. In the games, Army and Towson both won handily and would have increased their ratings while negatively hurting James Madison. But, the hidden bonus is they now can bring those rating points back into their region. Those points then become spread out over the entire region as the season progresses and teams win and lose.

For the ratings system to work, each game has to have a certain amount of value attached to it. In the system we will be using five different levels to rate the importance of any give game. The first level is the lowest level of importance; it contains all pre-season exhibition games. The second level includes all regular-season regional games, as well as cross-divisional exhibition games. Level three includes all cross-regional games and invitational based tournaments, like WinterFest. The fourth level includes all regional playoff games and the fifth and final level includes all national playoff games.
