HoF points after a championship

I'm pretty sure you get 100 Reputation points after each DC or TC you get. I got both championships but this season I only got 100 rp points. Could I have my 100 given to me or do I need to wait a bit longer?

you only get 100 points for 1st & 2nd in teams champ

You only ever get 100 reputation points, never 200.
If it was 200 I'd be ranked way higher than I am right now... :(

But if you only get the Driver's championship, do you still get 100 rp?
Or is there no reward for a driver's championship? That would be a little unfair. Not even £1 million donation for winning something.

no reward for drivers only teams champ

It's only ever been for the team championship.

The idea of money for winning has been discussed before, but is generally thought to be a bad idea as in most cases it would only make the strong teams stronger and would only help create a larger gap to the weaker teams.
