New NAF Glicko Rankings

Hi all,

Some exciting news for NAF members today, as we are launching our new Glicko ranking system, implemented by Nick Harding / mubo.

These rankings aren't designed to replace the Elo numbers you've been used to since NAF rankings began, they are simply a new way of processing NAF data and ranking coaches, and will run in parallel. The Glicko system is able to introduce new features that some coaches have wanted for many years, such as decay and greater reactivity. You can read more about how they work here and view the ranking page at thenaf.net here.

The system is currently in a 'soft launch' period, and if you experience any difficulty viewing the page or using the dropdown filters, please flag this up. The rankings will update on a monthly basis, and we hope the April update will be take us to a fully 'live' state. As we move forward, you can expect fun and interesting updates and developments to pop up on both thenaf.net and thetacklezone.net, and we'll advertise these as and when they become available.

Finally, we'd like to acknowledge Kyrre for his great work parsing the games played in the database so Nick could work with the data and implement the system.

Please join me in virtually patting Nick on the back for his fantastic work, and enjoy playing with the new system!



(P.S. Sorry for the English - but I thought this was cool enough to share! :D)

Hi all,

The April Glicko ranking update is live.

Along with the update to your numbers, we have some terrific new features for you this month.

- Dan / Wulfyn has written a lovely blog explaining the Glicko ranking system in more depth. If you have questions about mu, phi or the background of this system, read on!

- Nick / mubo has created a terrific rankings calculator where you can insert your Glicko ranking and see how it would change if / when you beat JimJimany's Wood Elfs, or when you play whatever local coach you know is attending your next tournament. This should help you chart your progress in real time, or even before time!

- The rankings themselves now feature a measure of how active rankings have changed compared to last month and where you sit overall for each race for which you have an active ranking. This should be pretty self-explanatory on the ranking page

As ever, thanks to Nick and Dan for all of their hard work. All feedback appreciated, and enjoy! :D
