Reputation

Would seem reputation has a mind of it's own, up until midnight my rep was 55xx now it's 52xx 

New season. It resets.

well if it reset at midnight why is not 5000. I've done nothing since 9pm last night ?

Well "reset" doesn't mean it is 5000 for every one again. Every one gets deducted half the points above 5000. So, first place is still first place, but the gaps have been narrowed.
It is kinda similar to calculation of ELO.

Now I'm more confused, I'm 3rd in the league and 2nd place has 8 points less than me

I guess I should have elaborated on the ‘reset’ ?. Well said.

From the game guide:


Reputation is how well you perform relative to expectations in the races you take part in. It starts for all managers at 5000 and increases or decreases based on your results. Similarly to level XP, it will increase by greater amounts if you are racing with managers with higher reputation levels than you.
Reputation is calculated entirely on the level of competition. Seeking out reputable rivals and populated leagues is very important to keep making progress with your own reputation level.
Not doing so can result in decreases in reputation even with good results. For example, let's say a top manager from the Hall of Fame whose reputation is 9000 goes and starts racing with total newcomer managers with 5000 reputation. It's so uncompetitive that simply participating in such an environment can be damaging to a reputation. So, a highly ranked manager could lose reputation even for victories there.
Another example would be if there are only two teams in a league. Whoever wins those races will also surely see a decline in reputation, again because they are not racing in a competitive environment.
The easiest way to keep your reputation on an upward momentum is to keep seeking out tough competition and challenging yourself. By racing stronger competitors, even a poor finishing position can result in reputation gains, because you won't be expected to win. Any competitive results in such an environment will also bring a huge boost to your reputation.

Reputation goes up and down based on the reputation of the people you race against and the reset thinks your losing this amount regardless of how well or bad you are doing. Much better just resetting everyone back to 5k every month.  ?

End of the month in the league 1st place 5032 & last place 5001 it's rating people on performance rather than striking off points willy-nilly. 

With your current system you would need league hosts booting people out every month to allow people with higher reps to join 

Acct lvl vs tier probably also matters. A manager in an active league won't have issues with reputation, just keep winning or meeting your sponsor targets and you're golden.

I'm not sure meeting the objective matters. ? 
I got plus 9 last night and I didn't finish in the top 2 like it wanted.
