By that method if you start anywhere in the last 5 of a field what is the point in racing? Youāre there just to give DR to others, unless you perform exceptionally, whereas someone who starts in the front 5 merely has to hold positions to gain DR.
From a bit of googling it seems your DR gain/loss is affected by the DR of the players you beat and lose to, which is fine, but doesnāt take into account you starting position, which to my mind is an oversimplification.
Hey ho, I must remind myself, itās only a game!
Copy/pasted from another thread from a while back. An explanation from Famine as he was conveying this to someone else - who kept arguing as memory serves - so some may be a bit out of context here, but you'll get the idea. I saved it as this seems to come up often. Regardless, this is how it works (I bolded the part that sums it up quite nicely in one sentence)...
____________________________________________________________
if you beat higher rated drivers (eg you are rated 1000 and everyone above you is rated 10,000) you are getting a DR change of ([80 + 900] / 500) from the drivers you beat. This works out to be a smaller number if the difference in DR between you and the other driver is smaller, if it was only a difference of 100 DR then it'd be [80 + 100] / 500 instead.
Therefore, beating higher ranked drivers gives you a bigger DR adjustment, as the difference between your DR and their DR is a core part of the final value.
DR is solely determined by your race finishing positions: a straightforward exchange of points between you, the people you beat, and people who beat you, scaled according to the relative difference in points between you.
But you do. The further ahead they are of you in terms of raw DR points, the less you lose, but you do lose points to them unless the difference is
enormous.
For every car you finish in front of you gain: 80 - ((Player DR - Rival DR))/500)DR
For every car you finish behind, you lose: 80 + ((Player DR - Rival DR))/500)DR
As you can see, unless the difference is in excess of 39,500pt, you'll lose at least one point.
In a race where everyone has identical DR, this is the change in points after the race:
1: +1200
2: +1040
3: +880
4: +720
5: +560
6: +400
7: +240
8: +80
9: -80
10: -240
11: -400
12: -560
13: -720
14: -880
15: -1040
16: -1200
Start 16th, gain one place, lose 1040 DR. You do not gain it, you lose it because fourteen other people took points off you and you gained them from one person.
The only time you won't lose DR is if you have no DR to lose, because your DR ranking is D and your rating is one point - and in your first five races at DR E - although people will still gain the appropriate number of points for finishing ahead of you. Otherwise it goes up and down exactly like I say.
This is literally how it works. It has been known and well established for more than five years. Where. You. Start. Does. Not. Matter.
