Field-Aware Contest Simulator

Pick which of your lineups to test. The sim drops them into a synthetic field, runs 2 000–10 000 score simulations per lineup, and ranks them by Cash %, Top 1 %, and Win % at the contest size you choose. The bottom-equity lineups get a DROP tag so you can prune before entering.

📐 How "Field size" ≠ "Contest size": Generating 400 000 fake opponents for the Milly Maker would take hours. Instead we sample 200–1 000 representative opponent lineups (the Field) and then scale your Cash % / Top 1 % / Win % up to the actual contest size using extreme-value statistics (Gumbel). That's why a Milly Maker Win % comes back as 0.0001 % even when your lineup looks strong — there are 400 000 entries trying to beat you.
