This is way more lengthy than I wanted and hope you don't get bored...
First of all, I hope everyone is enjoying the rankings… Now let’s describe in a little more detail how those rankings come about, and why as some have noticed, there is some difference in your league ranking as compared to the site ranking… My first disclaimer for the actual accuracy of these ratings is that not all teams have played the same amount of games, so a team that has a record of 90 or 81 will score higher in winning percentage than a team with a record of 71 due to the nature of the scoring system… By the way, after the games of 1/3/2012 we will all have the same number of games played, so this will correct itself… As I think I posted in each of your league forums, I used a basic system of measurement for calculating rankings… I used winning percentage, Margin of Victory, and Strength of Schedule… Further, they are compensated by the values chosen by me as modifiers… Winning % is multiplied by 30% MOV is multiplied by 10% SOS is multiplied by 60% Meaning that I placed more value on SOS as a determining factor with the thought that it compensate some for the BOTs… You will also see your team listed by rank, name, Avg Rank, and Points Most folks will assume Avg Rank has something to do with the ratings, but the fact is, they are just a quick comparison for you to see where you rank within your league for the scoring categories used… It’s the points that actually matter, but want you to know how the Rank is calculated as well… Rank and name are obvious Avg Rank is simply your rank in each category multiplied by the modifier in each category… WIN % rank X 0.3 + your MOV X 0.1 + your SOS X0.6 and added together = your Avg Rank… Points is the exactly the same as Avg Rank except it is your point total in each category multiplied by the modifier in each category… I want to use Buffalo’s team Lucea Cardinals from Sea Devils 1.1 as an example to both show how the teams are rank as compared to their own league and how they move or not when compared across all leagues… Lucea is ranked # 5 in SD 1.1… Impressive by the way…!!! For winning % he is ranked # 4 in his league… We take 4 X 0.3 = 1.2 For MOV he is ranked # 4 again… We take 4 X 0.1 = 0.4 For SOS he is ranked # 16… We take 16 X 0.6 = 9.6 His Avg Rank becomes 1.2 + 0.4 + 9.6 = 11.2 Compare this across the the site and his numbers are this… Lucea is ranked # 26 in RZA… Also Impressive…!!! Win % rank is 26… We take 26 X 0.3 = 7.8 MOV rank is 16… We take 16 X 0.1 = 1.6 SOS rank is 144… We take 144 X 0.6 = 86.4 His Avg Rank becomes 95.8 So let’s get to the points… I should explain at this point that the scores are based on a 100 point system… As we saw Lucea is ranked # 4 in winning percentage… In his league this equates to 87.5 points… You see 2 teams in the league have 80 records equaling 100 points, meaning a 08 record would equal 0 points… Everyone else in the league will receive points on a sliding scale from 0 to 100 for winning percentage… Take his 87.5 X 0.3 again which = 26.25 He is also ranked # 4 in MOV which equates to 89.50 You see the largest avg margin of victory in his league is 47.7 by Leeds the lowest avg margin of victory is 32.5 by St. Louis So Leeds gets rank of 1 and points of 100 in MOV (margin of victory) and St. Louis gets rank of 32 and points of 0 in MOV... Everyone else is assigned points based on their differential using the 100 point scale... You can see there is 80.2 point differential in avg MOV so the scale is not linear, and thus with a MOV of 39.3, it’s not simply 47.7 – 39.3 = 8.4 and therefore 100 – 8.4... There is some math involved here due to the nonlinear scale… So take his 89.5 X 0.1 = 8.95 SOS is done using same scale and has much different resulting point total, because strength of schedule is determined using percentages so the math gets a little more difficult... We saw his SOS rank at 16, which equates to 85.22 points His actual SOS criteria is that he has played teams with an avg winning % of 49.64% The top ranked team in SOS in his league is a BOT (Team 1.1.12) having played teams with a winning % of 58.25%... The system then using the 100 point scale assigns 100 points to 58.25 and 0 points to 0%, since it cannot compute negative percentages… As you can see the scale is much smaller… So we take 85.22 X 0.6 = 51.132 His total points for the league are 26.25 + 8.95 + 51.132 = 86.332 Doing this for RZA ranking goes like this… His rank for winning % is 26 across the site for a point total of 87.5 just like in his league and this would be true for everyone… So same for league score we get 87.5 X 0.3 = 26.25 His rank for MOV is 16 for a point total of 82.64… This is a bit of change from the league ranking since the criteria for 100 is no longer 47.7, but 59.4… Also the bottom has changed to – 56.6… Wow over 100 point differential, and still not a 1 to 1 ratio now… It’s actually 116 point differential which even lowers the score… So let’s take his 82.64 X 0.1 = 8.264 His rank in SOS was 144 for a total point score of 80.98 Again a bit of a change since we now not only compare him to 31 other teams and a 100 point scale at 58.25, but now all other 255 teams on a 100 point scale measured against 61.3%. Talk about a tough schedule… So we take 80.98 X 0.6 = 83.102 Just missing the top 25… Congrats… Remember all that these ranking are all done manually and there is always a possibility of an error on my part…. Please don’t hesitate to raise your questions, and keep me straight… Thanks to Buffalo and his questioning attitude for getting me corrected on the latest RZA top 25 ranking… And to the many others of you that have asked for this…

Thanks for your job and good explanation.
Do you calculate the rankings manually or using a software, where you only put in all teams and the results?

It's actually a program called the Football Rankulator, and it does the math... Entry of all teams, schedules, and scores are manual since the thing is designed specifically for College football... I've even asked for a template to use from the owner, but he says just as I that it was not designed to be a stand alone generic software, so no such template or upload capacity was developed... With the exception of the college stuff through his site... This can be done in excel, but I'm finding it easier to do with the software since it does the math and I don't have to admit that I'm too lazy to do it... OOPS, maybe I just did...

The problem with being able to do rankings of those leagues, is that they are so volatile, with new members signing and some leaving, team names change regularly... With this being all manual load for teams it is more time than I have available to maintain... Glad you found it nonetheless... And best of luck to you...

aye... skimmed over too much of the intro.. I see you posted the rankings in the division forums. I was thinking that they were some under a tab in the front office menu or games menu.
Honestly though this would be neat to have in the Mag section. Could be its first real asset to the game I think.

The news compares the given rankung with a former ranking, which i wasn´t aware of. Does anyone knows where i can find this first ranking?
Nice to be on #11 though
