So I was trying to get to last place.
First season was tied at 0 points.
The plaque at the end showed 9th, so I tanked a second season.
Then at the end both plaques showed 10th, so I proceeded to win the next season.
But I did not get the achievement.
And the plaque of the previous turned into 9th place, which was really disappointing.
I don't really want to do this all over again, especially I am at the last season, so no more chances at getting the achievement now
