The number of career points you get for stage victories has been adjusted.
New formula:
(X / 10) where X = number of participants
Old formula:
(X / 10) multiplied by (X-position in final standings) / X where X = number of participants
For a stage victory you're guaranteed to get 0.1 career point per participant.
So with 3000 participants you get 300 career points per stage victory.
This is no longer reduced by your position in the final standings.
