Glossary

Written by Jordan Chand

Adj Own. Adjusted Ownership. A player's projected ownership adjusted for how they perform in the simulations. Higher than My Own means over-owned. Lower means under-owned.

Cash Rate. The percentage of simulations in which a lineup won any prize.

Contest Flashback. Re-simulates a finished DraftKings contest 100,000 times using the lineups everyone actually entered. Produces Flashback ROI.

Contest Sims. Simulate your contests tens of thousands of times using their real size, payouts, and field lineups. Produce Sim ROI.

Correlation slider. Controls how strongly SaberSim favors correlated players when building. Higher means more stacking.

Delta Exposure. The change in a player's exposure between your original lineups and your current ones, shown during Late Swap.

Dupes. The number of times a lineup is expected to be duplicated by other entries in the contest field.

Entries file. The CSV from your DFS site listing the contests you've entered. Uploading it tells SaberSim what to build for and what to fill.

Entry exposure. The percentage of your the lineups currently saved to your entries file that contain a player.

Exposure. The percentage of your lineups that contain a player. Set with the Min and Max exposure columns.

Field lineups. Simulated sets of opponent lineups built to match how people play at a given entry fee and contest type. What Contest Sims and Saber Score run against.

Flashback ROI. A lineup's ROI from Contest Flashback, measured against the real field.

Full Swap. Rebuilds every open slot in your lineups after lock from new simulations, keeping locked players in place.

Global Max Exposure. A single cap on how often any player can appear across your whole portfolio.

Late Swap. Updating lineups after lock. Quick Swap and Full Swap are the two ways to do it.

Leverage. Your exposure to a player minus their projected ownership. Positive means you're over the field. Negative means you’re under the field.

Lineup group. A folder of lineups, usually attached to one or more contests from your entries file.

Lineup group template. A rule set that builds lineup groups from your entries file automatically.

Lineup Pool. Every lineup SaberSim built for the slate, before any are assigned to contests.

Min Uniques. A diversity setting that forces each lineup to differ from the others by a set number of players. Portfolio is the default instead.

My Own. The ownership projection: how often SaberSim expects the field to roster a player.

Old Saber Score. The previous Saber Score formula, built from projected score, 95th percentile outcome, and ownership.

Percentiles. A player's range of outcomes across the simulations. 25th is floor, 50th is median, 85th to 99th is ceiling.

Pool exposure. The percentage of lineups in your entire pool that contain a player. Descriptive only.

Portfolio. The default diversity setting. Uses the Portfolio Diversifier.

Portfolio Diversifier. Assigns lineups from your pool to contests by solving your whole portfolio at once for the best mix of upside and coverage.

Portfolio+. Portfolio diversification with full Contest Sims for each contest.

Quick Swap. Replaces ruled-out players in your lineups while keeping the rest intact. Triggered by the red icon in the upper left.

ROI. Return on investment. Average profit or loss per dollar entered, across all simulations.

ROI StdDev. How much a lineup's ROI swings across simulations. Higher means more volatile.

Saber Score. A lineup's ROI from a generalized Contest Sim against an internal field.

Sim Diversity. Sets how many simulations each lineup is built from. Higher means fewer simulations and more variance.

Sim ROI. A lineup's ROI from Contest Sims, measured against the specific contests in your entries file.

Stakes buckets. The field lineup sets by entry fee: Low Stakes ($4 and under), Flagship ($4.01 to $30), Med Stakes ($30.01 to $99.99), High Stakes ($100 and up).

Win Rate. The percentage of simulations in which a lineup finished first.
