To sum up...if I understand, our formulas are exactly the same except you compute the "multiplier" based on the amount of people left in the game at the time a loser is being computed when I was using the same multiplier (in the case of a 4-player game...the root of 4) for EACH round of computations. Perhaps that was why it was swinging wildly as it got down to the Last computation.

Do I have it right, now?

Yes,.
Just remember its the Square of the remaining players (n-1), not total number of players. So the looser in a 4 player game will get the root of 3 as the multiplier, not the root of 4

Good. Just so we understand it. When I get some time, I'll run it through the "new" formula. I think it looks a bit better.

Thanks for the feedback and we'll get these Ratings caught up soon.

Gotta run right now...was just checking the board before I signed off.

Hope I have understood your proposal properly Slynky. If I am right it will not work well on larger games.

Example, 10 (1000 point) players :

Slynky: 108 / 76 / 17 / 0 / -13 / -23 / -31 / -39 / -45 / -51

Mine: 75 / 43 / 25 / 11 / -1 / -12 / -22 / -31 / -40 / -48

If the numbers of points is to low, the easiest way to fix it is to just multiply everything with some percentage (based on gamesize of course ).

I appreciate the interest and suggestions. Truth be told, I was trying to find a nice spot between what Geo suggested and what Grandpa Kim would like to see. But, looking at your spread(s), I think it looks a bit better over all as my exponential stuff seems to create too wide of a spread.

So, if I may ask, how about a detailed math example of your approach for a 4-person game where all players have 1000 points (where we all know 16 points is the gain/loss)? I just want to make sure I understand it.

Hey Joachim,

I think Asmala forgot about our game LOL. I hope he didnt go on vacation.

Games needing rating computation (in this order):

4 player multi-player (Alneyan, Belisarius, Gecko, Slynky)

Alneyan vs Primitive

Joachim vs Warlord Ragnarok

Primitive vs RexTorres

Parabolize vs Joachim

Electrum vs Primitive

Slynky vs Joachim

Working on the Ratings now. Here is the re-work using the "GeoSlyPri" formula henceforth referred to as the Geo-Slippery formula:

Alneyan +40
Slynky -2
Belisarius -14
Gecko -22

I think this looks much better as the spread looks similar to the "1000" point baseline calcs BUT we note that Alneyan was nearly the lowest rated player (and therefore got quite a few points for his 1st place finish). Beating me alone gave him 21 points on the Last computation (besting Geo's record of getting 20 points from me)!

Again, points would be nearly the same as won and lost but because of rounding...we have a 2-point disparity.

I'll be making all the other updates now that this "roadblock" is out of the way. Thanks for the interest and input.

Incidently, I will count a multi-player game as one game...as people leave, their game count will be upped by one while the players still in a game will not get an additive. When all is done, everyone will have one game added.

Working on the site now...there is a new points leader!

Uhhh, could we maybe come up with a better name?

You mean for the formula? LOL .
