Any progress on the ranking module?

The ranking module on this site is currently in beta testing with plenty of results already entered. If there are no glitches in the system, it should be finalized rather soon.

If time permits, please release it to open beta already!

I think some of the maths on that page isn't correct. Well, it probably is, but the rating point function isn't the right one.

It should be :
[90/30/0]*(2*log(NB_PLAYERS)/log(15)-1+coeff) + 8 * NB_GW + 4 * NB_VP + 5
where [90/30/0] works this way: use 90 for the winner, 30 for finalists, and 0 for non-finalists
NB_PLAYERS is the number of players
NB_GW is the number of Game Wins of the player
NB_VP is the number of Victory Points of the player
coeff is: 0 for standard tournaments, 0.25 for CCQs and Nationals, 1 for Continentals

With this evaluation, I get (for tournament #4 of 2013 and for the winner):
(90 * (2 * log(19) / log(15)) - 1 + 0) + 8 * 3 + 4 * 16 + 5 = 198.7 (should round up to 199).
The page displays 170 . Did you get that value from the Archon, or is it calculated by the server?

I will let Santh take a closer look at this.
it's possible that some of the rating point may be different as we are using other coeff for Polish league purposes.

I will get back to you soon.

it's fine. it's my point of view, i show i the table whole score on tournament and FVP shows how final was going.
so to explain Winner before final had 1GW 6VP, he won final with 5VP, so he has at the end 2GW 11VP what you can see.
=90*(2*LOG(19;15)-1)+8*2+4*11+5=170.71, but i round id down

ps. my script calculate it all, its easier then uploading whole archon file, i use only tournament info, maths, rounds, and optimal sitting, and better because some older version of archons have bugs and don't calculate RtP correctly.
