Weekly P-Rankings Page
Starting with 2010, I am setting up a new weekly award: Highest P-Ranking. It is calculated from Sunday 6:00pm to Sunday 5:59pm.
In this Propability-based ranking system every public ranked game is evaluated. It's quite simple how to get a better ranking: Just win against better players ;-)
Every Monday morning 00:00 MET (in summer MEST) the rankings are reset to initial value of 800. The same time the top players are recorded into a statistics page.
You can watch the Rankings any time by visiting this site and takeing a look on the left side P-Rankings block.
The first 3 places every week will get the awards pointing to player list page:
This ranking system is based on ELO computation from chess tournaments.
Some Terms:
Ro = Rating old
n = number of Opponents
Ri = Rating of individual opponents
Rn = Rating new
P(D) = Propability to win vs one player with Ratingdifference D (see table)
P = Position gained
Pe = Position expected
Formula:
Pe = n - SUM(P(Ro - Ri)) + 1
Rn = Ro + 800 * (Pe - P) / (5 + n)
If Rn is less than 0, it is set to 0
0-3 50 50 69-76 60 40 146-153 70 30 236-245 80 20 358-374 90 10 4-10 51 49 77-83 61 39 154-162 71 29 246-256 81 19 375-391 91 9 11-17 52 48 84-91 62 38 163-170 72 28 257-267 82 18 392-411 92 8 18-25 53 47 92-98 63 37 171-179 73 27 268-278 83 17 412-432 93 7 26-32 54 46 99-105 64 36 180-188 74 26 279-290 84 16 433-456 94 6 33-39 55 45 106-113 65 35 189-197 75 25 291-302 85 15 457-484 95 5 40-46 56 44 114-121 66 34 198-206 76 24 303-315 86 14 485-517 96 4 47-53 57 43 122-129 67 33 207-215 77 23 316-328 87 13 518-559 97 3 54-61 58 42 130-137 68 32 216-225 78 22 329-344 88 12 560-619 98 2 62-68 59 41 138-145 69 31 226-235 79 21 345-357 89 11 620-735 99 1
In this table, you can see three columns the first indicates the difference between the old rating values, the second indicates the winning percentage for the better player, the third the winning percentage of the weaker player.
The table in fact represents a gaussian distribution function.
