FORMULA FORMULA ON THE WALL
« on: January 07, 2011, 01:32:21 AM »
Please answer , what I'm sure is an ice age topic , how do the formulas work and what will be the best or most common formula.
I want a formula that can give scores from 4 to 80 players depending on the night , we are a very large club in South Africa and not all of the same players plays everyday non the less would i like to award points as the year goes along.

Your help and patience be greatly appreciated. ;D

A very basic formula, Andrew, would be "n-r+1", which awards points based upon the number of people who show(n), and their rank (r). However, that could lead to volatile changes each week, so you may want to look at some others, which I cannot think of off hand.

A simple variation on this would be:

(n - r + 1) * log(n)

This would give more weight the larger the tournaments.  For example, for a tournament of 8 players, points would be awarded as:

1st: 16.64
2nd: 14.56
3rd: 12.48
4th: 10.40
5th: 8.32
6th: 6.24
7th: 4.16
8th: 2.08


For a tournament of 50 players, points would be awarded as:

 1st: 195.60
 2nd: 191.69
 3rd: 187.78
 4th: 183.87
 5th: 179.95
 6th: 176.04
 7th: 172.13
 8th: 168.22
 9th: 164.30
10th: 160.39
11th: 156.48
12th: 152.57
13th: 148.66
14th: 144.74
15th: 140.83
16th: 136.92
17th: 133.01
18th: 129.10
19th: 125.18
20th: 121.27
21st: 117.36
22nd: 113.45
23rd: 109.54
24th: 105.62
25th: 101.71
26th: 97.80
27th: 93.89
28th: 89.98
29th: 86.06
30th: 82.15
31st: 78.24
32nd: 74.33
33rd: 70.42
34th: 66.50
35th: 62.59
36th: 58.68
37th: 54.77
38th: 50.86
39th: 46.94
40th: 43.03
41st: 39.12
42nd: 35.21
43rd: 31.30
44th: 27.38
45th: 23.47
46th: 19.56
47th: 15.65
48th: 11.74
49th: 7.82
50th: 3.91


To increase the amount of points awarded AND the distance between ranks, increase the log() argument.  Examples:

(n - r + 1) * log(n * 2)

or

(n - r + 1) * log(n * 10)

or

(n - r + 1) * log(n * 100)
