How the contest simulator works
The contest simulator is a Monte Carlo engine that plays out your lineups thousands of times against a realistic field of opponents and the contest's real payout structure.
Reading your sim results
After a simulation, every lineup carries a set of contest-aware metrics; knowing which ones to sort by is how you pick the right lineups for the contest.
