OGS Glicko to Rank
// ==UserScript==
// @name OGS Glicko to Rank
// @namespace http://tampermonkey.net/
// @version 0.1
// @description Convert Glicko ratings to dan/kyu ranks.
// @author Andy Olsen
// @match https://online-go.com/player/*
// @grant none
// ==/UserScript==
// This script modifies the user profile page and replaces the Glicko ratings with traditional dan/kyu ratings.
//
// Formulas:
// glicko = 850*exp(0.032*r)
// r = ln(glicko/850)/0.032
//
// Table to convert from r to dan/kyu:
// Each entry is the weakest of that rank. So r=30 is the weakest 1d.
// r=38= 9d
// r=30= 1d
// r=29= 1k
// r= 0=30k
//
// This script displays kyus as: strong 1k = -1.0k, weak 1k = -1.9k.
// OGS displays this as: strong 1k = -0.0k, weak 1k = -0.9k.
// I prefer it this way, same as AGA ratings. But maybe it would be better to
// be consistent with OGS. Feedback welcome.
