The Workshop
Workshop (top nav) is where you backtest: load a past slate exactly as it was frozen at lock, build lineups against it with today's tools, and score them against what actually happened.

Pick a past slate
Use the date calendar to pick a day, then choose from that day's archived slates. The pool loads with the projections, salaries, and ownership as they stood at lock — a faithful replay, not today's numbers.
Build like normal
The Workshop mirrors the live build screen: lock/exclude, boosts, Advanced Options (General / Team Stacks / Groups), lineup count, Build. Workshop builds save to their own tabs, separate from live builds.
Score against actuals
Completed games mean actual fantasy points exist. Scored results show, per lineup, the actual score alongside the projection.
- DraftKings slates score against archived contest payouts — the portfolio summary reports how the set would have cashed.
- FanDuel slates have no archived contests; enter the contest's Top Score and Cash Line by hand and the panel scores the set against those benchmarks (a 5-metric summary). Your inputs persist per slate.
A backtest replays one night. A settings change that wins on a single slate may be noise — treat Workshop results as evidence to accumulate, not proof.
The Workshop honors the same platform toggle as the main screen — DK and FD archives are separate.
