DFS Simulation Output Explained: Every Column

By Splash Play Staff ยท A guide to reading the tools

Every DFS simulation column has a unit, and most misreadings come from mixing them up. A projection is in fantasy points. Top10% and Cash% are how often something happened in the model. ROI is a modeled return that depends on the entry fee and the payouts. Read the unit before you sort by the column.

The columns

ColumnWhat it measuresThe common mistake
SalaryPlayer cost in a player view; total lineup salary in a lineup exportUsing a DraftKings salary on a FanDuel slate
ProjForecast fantasy points in this site's scoringReading a forecast as a result
Top10%How often the lineup had a top-10 finish in the modelTreating it as a points percentile
Cash%How often the lineup finished in the money in the modelTreating a cash as a profit
ROIModeled return, given the fee and the payout structureReading it as a return you will get
Sim%Simulated lineup usageReading it as your own exposure

The NFL lineup export carries most of these beside the roster slots: Salary, Proj, Top10%, Cash%, ROI, Origin, FieldSeats, MetricBasis and Worlds. The last four describe the run the numbers came from, so keep them with the file. Other sports and views show a different set.

A percentage needs a denominator

Say a lineup reaches a score 7 times in 100 simulated slates. That is 7%. The 7 means nothing without the 100, which is why the export records the basis and the number of simulated slates beside each rate. When you compare two lineups, compare them on the same basis.

Cashing is not profit

A made-up example: you enter for 10 and the lineup pays 8. That counts as a cash, and you lost 2, a return of minus 20%. A lineup can cash often and still lose money if its cashes are small ones. Cash% tells you how often. ROI is the column that accounts for how much.

ROI depends on the contest

The same lineup has a different modeled ROI in a different contest, because the field and the payouts change. An ROI figure is tied to the contest it was computed for. It is a model's expectation under its assumptions about the field. It is not a forecast of your bankroll.

Before you sort

  1. Check the site and slate.
  2. Note which run the numbers came from.
  3. Decide which column answers your question: cashing, finishing at the top, or return.
  4. Then sort.

Where to see it

Simulation results are part of Squirt Squad VIP and Apex. Open the NFL tool for the current slate, read the field guide for the step-by-step workflow, or compare memberships. Simulation results are model outputs and do not promise a finish or a payout.
