Point Tallying In e-regata
Important! All limits which are discussed below are applied to a one regatta.
How to get points
Every race gives you a possibility to get some points.
We have two formulas to calculate your points.
For the first N races we use Formula 1:
Points = Racers - Position + 1,
where Racers - number of boats in a race, Position - player's place in the race.
Number of points you get for the races, counted by Formula1:
|

| Place |

All extra races (>N) are scored by Formula 2:
Points = 0.25* (racers - 1) - position + 1,
where Racers - number of boats in a race, Position - player's place in the race.

Important! Number of N races can't be known before the race have been held, because it's calculation depends on the number of boats in every race.
In e-regata we have maximum 8 boats per race and regatta lasts for 7 days. So, the maximum number of opponents in the calculations according to Formula1 is 672 (8 boats*7 days*12 races per day). If we divide the maximum number of opponents by the number of boats in a race, we'll get limits on the number of races in frames of one regatta:
|
Number of boats in a race |
|
8 |
7 |
6 |
5 |
4 |
3 |
2 |
| Number of N races |
84 |
96 |
112 |
134 |
168 |
224 |
336 |
In other words,
if you had raced always with 8 players for 7 days of regatta, the points for your first 84 races will be counted by the Formula1, all extra races will be calculated by the Formula2;
if you raced always with 7 players for 7 days of regatta, the points for your first 96 races will be counted by the Formula1, all extra races will be calculated by the Formula2;
and so on.
If you noticed that the sum of your points begins to decrease, it means that you have exceeded the weekly limit of races and your position in the ranking because this can deteriorate.
E-regata's engine calculates race limits and then race points automatically. Therefore all claims that you received less points than you deserve, or that points have been lost somewhere, are not wealthy and will not be considered.
General rating calculation
User's Rating is calculated for every regatta with his participation by this formula:
Double Rating = 300 * Math.Exp(-(rank - 1)*10 / members)
where members - is a number of sailors in the particular regatta.
Total rating is a sum of ratings (earned points) for all previous regattas that fall (and finished) within the previous 60-day period. If the player missed some regatta that was held in this period of time, he earns 0 points for it.
The procedure of the overall rating calculation runs when a new regatta starts.
