A real slate's players — salary, position, team, kickoff state — with projection, ceiling, ownership, and a coverage badge per player, plus a drawer with the full distribution, workload, and where every number came from.

Private, per-user shifts to a player's projection or ownership estimate. Praedictum's own baseline is never touched — every screen will show the baseline, your adjustment, and the effective value used to build your lineups, side by side.

An exact solver builds the best legal lineup — and the next-best, and the one after that — under your locks, excludes and salary cap, run in the background so a long search doesn't block your browser.

Runs your lineups against one real, human-observed DraftKings contest today (NFL $800K Play-Action [20 Entry Max]; $3 entry, 317,082 entries, 35 payout tiers), reported as ROI with both kinds of uncertainty shown separately, never blended into one number. Its screenshot wasn't captured, so it needs re-observation if it's ever in question.

Chooses a set of lineups for a contest's entry cap — rewarding upside, limiting exposure to any one player — compared against the plain baseline of entering your single best lineup every time.

Writes the file DraftKings' upload page accepts, with player ids copied exactly from the slate DraftKings published. Some of what the format needs (column order, that a bare player id works) has been checked against a real downloaded template; a few things (file encoding, line endings, whether the header row is required) are still assumptions, and the export will name exactly which is which.
