Base it off of the glicko-2 paper that is linked in the references. I was attempting to do it off of the algo specified in the wiki article, but a lot of important details are left out. Also glicko two has lots of improvements. — Preceding unsigned comment added by 134.134.137.71 (talk) 18:55, 11 April 2012 (UTC) More detail would be appreciated, about these important details left out, and the improvements contained in Glicko 2.

The article states that "Both Glicko and Glicko-2 rating systems are under public domain". Is this a meaningful statement? Glicko is just a series of mathematical formulas, and mathematical formulas are not subject to copyright. JakubMarian (talk) 21:39, 23 September 2014 (UTC)
In the first step, if a player played in the previous rating period, should t be 0 or should it be 1? --Twixter (talk) 18:58, 25 April 2019 (UTC)
Quoting from Glickman's pdf, "One practical problem with the Glicko system is that when a player competes very frequently,his/her rating stops changing appreciably which reflects that the RD is very small. This may sometimes prevent a player’s rating from changing substantially when the player is truly improving. I would therefore recommend that an RD never drop below a threshold value,such as 30, so that ratings can change appreciably even in a relatively short time."
This being the case, perhaps the formula in step 3 should be
