Calculating explained

Calculation of Points

You get Points for each BBC game you play, according to the following table:

Place	Points if game is
	Step 1	Step 2	Step 3	Step 4
1	10	20	30	40
2	9	18	27	36
3	8	16	24	32
4	7	14	21	28
5	6	12	18	24
6	5	10	15	20
7	4	8	12	16
8	3	6	9	12
9	2	4	6	8
10	1	2	3	4

Calculation of Score

If P is the Number of Points you got and G is the Number of Games you played, the score is calculated with the following formula:

So its "Points per Game" multiplied with a coefficient. This coefficient is 1 in the first game, and increases by 1 if you play twice as much games (for instance it is 2 after 2 games, 3 after 4 games, 4 after 8 games, 5 after 16 games etc.). Why did we choose this formula? Because it gives Players who play more often a little bonus, but high scores requires good results too (because of "Points per Game").

For People who understand PHP, here is the formula copied from the source code:

function calcscore($points, $games)//$games is number of played games
{	
    if($games<=0 or $points<=0) return 0;
    $coefficient = 1 + log((float)$games, 2);//logarithm with base 2
    $score =(float)$points* $coefficient /(float)$games;
    return (int)($score*1000);
    //score will be divided by 1000 in ranking
}
