Slates on file

Upload a slate

FanDuel exports one CSV per slate, so a week normally takes several — Thursday, the Sunday main, Monday. The slate id, its games, the day, single-game vs multi-game and the roster shape are all read from the file; the upload is refused if the teams do not play the week selected above.

No CSV? paste salaries

Ownership

Ownership is otherwise SIMULATED — a field of optimal lineups built on perturbed projections. That is an assumption with no ground truth behind it. Real contest ownership pasted here replaces it outright and is strictly better.

Contest these numbers came from

Required. Ownership measured in one contest does not describe another, and a paste against the wrong id matches nothing rather than failing loudly.

Copy grabber puts a one-line bookmarklet on your clipboard. Make a new bookmark, paste it as the URL, then click it while the finished contest's player table is on screen — it reads the table the page has already rendered and copies it back in this format. Nothing is sent anywhere and no login is involved; it is the same copy you would do by hand.

Based on

Stack by team

The QB's team in each lineup, and how many of his pass-catchers came with him.

Stack by type

Shape of the correlation, not the team. A bring-back is a player from the opposing side of the QB's game.

Team exposure

Every roster slot filled by that team, stacked or not.

One lineup, built by hand from the same pool the optimizer uses. Locked slots are respected by Generate random and Fill best available, so you can pin the players you want and let the rest fill around them. Excluded players (X in the Player Pool) never appear here.

Leverage — your exposure vs the field

Over = you own more than the field. Under = the field owns more than you.
