I was wondering how the current top ranked reputation player has 10,000 pts ? 1 championship , 1 league, 139 races, 29 wins, 87 podiums and 17 poles. Compared to my 26 championships, 4 leagues, 951 races, 249 wins, 597 podiums and 126 poles.
I first reached 10000 reputation after 136 races (that's 8 seasons). You have to be in a league with a high average reputation, and beat your competition very consistently. My league's Elite tier had a 8600+ average reputation when I got to 10000 reputation, and it has a 8800+ average reputation today. I also never had a retirement, and never had both my driver lapped in a race ever. If you maximize absolutely everything (which attributes to spend design points on, which aspects to spy, race strategy, driver training strategy, etc.), it's possible.
I spent 1 season in Rookie, 2 seasons in Pro, and 5 seasons in Elite before winning my first Elite championship. But I'm not new to this game; I've had about 2000 races in total on all 10 of my previous accounts, so I know my way around this game. I've also been #1 in the HoF briefly 3 times back in 2016 (when the #1 reputation was around 9600).
It seems that your league's average reputation is somewhere around the high 7000s. That's not quite enough for you to get to 10000 reputation, since reputation is calculated according to the Elo rating system. If you beat lower rated managers, you don't gain much. I just had a bad race in my league where I only finished 8th and 11th out of 32 cars, and my rep dropped from 10000 to 9993. My drivers' average position was about in the top 30% that race and yet I lost 7 reputation. That's the Elo rating system for ya.
