DR specific

Does anyone know the exact way your DR ranking is calculated?

I've won races, had clean races and it seems to still stay a D. I'm currently D / S .... I had no problems getting my SR up to an S .

I'm not sure if anybody knows for definite how it is calculated but it seems to be that finishing higher than your grid position, beating higher rank drivers, the higher the finish position and general pace (fastest laps/qualifying time/total race time) is what contributes to an increase in driver rating.

If a person is D for example and gets matched with other D drivers but their pace is similar and they don't gain many positions, set fastest laps or win then they may not increase their rating.

This could all be wrong though.
