The trick to the leaderboards: you get placed in a league with people that had more or less the amounts of points you had in the previous leaderboards. So, if you want an easy-breezy-leaderbord event: skip 1 or 2 in whole, don't go for the milestones, get as little points as possible. Then, the next boards will be easier and easier.
The harder you try, the harder your opponents will be.
Atleast, that's my theory.
