Needs a name column and Proj. Uses an ownership column (Total Own, Own %, Large Field…) and Ceiling when present. Most projection exports work as-is.

Fill unprojected players with DK season averages Off by default when you load projections, and it should usually stay off. AvgPointsPerGame is a whole-season average, not a projection for this week — a $4,000 backup carrying a 16.3 average reads as 4.08x value and the optimizer will take him every single time.

02 OPTIMIZER SETTINGS

GENERATE LINEUPS builds with the rules below. ⚡ GIVE ME THE OPTO ignores every one of them and returns the highest-scoring lineups DraftKings' own rules allow — the denominator for % of Slate Max, and the right button for cash games.

Max SalaryDraftKings cap

Min SalaryLower spend = fewer dupes

Lineups1–1000

Max Exposure %Common default 50%

Randomness ±%Common default 5%

Max Player OverlapShared players between any two lineups. Range 0–8

CORRELATION & STACKS

QB Stack — pass catchers Players from the QB's own team. 0 = off. Industry presets are QB+WR and QB+WR/RB.

Bring-back From the opposing team in the QB's game. Chalk bring-backs are conditional — they help on some slates and hurt on others, so decide week to week.

Min players in one game Game stack floor. 0 = off.

Count TE as a pass catcher

Count RB too (QB+WR/RB)

TEAM & GAME LIMITS

Max players per teamDraftKings' own limit is 8

Min unique teamsFewest different teams in each lineup. 0 = off

One RB per team

ON by default

No RB vs opposing D/ST

Your RB and D/ST never face each other

No QB vs opposing D/ST

No WR/TE vs opposing D/ST

Keeps your offense from facing your own D/ST Keep out of FLEX

OWNERSHIP & LEVERAGE

Max total ownership % A full Classic slate sums to roughly 900% across 9 slots. 0 = off.

Min total ownership % Stops the solver hiding in unplayable chalk-free builds

Max product ownership % Shown as the 9th root — average ownership per slot. Lower = more unique. Showdown research (.43 r² vs dupes); that source says dupes matter far less in Classic.

At least N players under X% owned

Calibrate to this slate — set a threshold to see the live count.

PLAYER FILTERS & PROJECTION BAND

Min projectionDefault 0.01

Min value (pts per $1,000)Projected points per $1,000 of salary. 0 = off

Projection band — low % of max Showdown research: max-entry players put 53.7% of lineups in the 90–95% band vs 41.8% single-entry

Projection band — high % of max 0 = off. This is the slowest rule — expect a pause.

LOCK & EXCLUDE
