The sharpest ownership projections in DFS golf — and the tools to leverage them.
SlateSims pairs a purpose-built, continuously back-tested ownership model with hole-by-hole simulations, an optimizer, and exact contest-ROI math. One platform, fully automated, at a fraction of the price of the multi-sport incumbents.

Why SlateSims wins
In DFS golf, edge comes from leverage — being over or under the field on the right players. Leverage is only as good as the ownership number it's measured against. That number is what we obsess over.
Accuracy-first ownership
A LightGBM model, ensembled and back-tested every week. We publish our error (MAE) and show our work — nobody else in the space does.
Fully automated
DraftKings salaries, player IDs, OUT/WD status, and exact payouts pull themselves. The model retrains on its own. No weekly CSV grind.
The whole stack
Projections → hole-by-hole sim → optimizer (Sim Score) → contest ROI on exact DK payout tables → entries-file upload. SaberSim-grade, one tab.
Bring your own edge
Power users feed their own SG, odds, or projections and the model and sims run on their numbers. No competitor offers this.
Everything you need to attack a slate
🎲 Hole-by-hole simulations
Every golfer's tournament simulated thousands of times — birdie streaks, bogey-free rounds, eagles, the missed cut. Real boom/bust shape, not a flat projection with a guessed standard deviation.
🏆 Optimizer + Sim Score
Build hundreds of lineups ranked by a leverage-aware score that blends projection, ceiling, and ownership. Per-player min/max exposure, locks, and bans.
💰 Contest ROI
Score every lineup against an ownership-weighted field on the exact DraftKings payout table — expected ROI, cash %, and win % before you enter.
✋ Hand Build
For single-entry players: drop golfers in one at a time and watch your salary remaining update live. Save lineups and export straight to DK.
📈 Published accuracy
A live page tracks our ownership MAE vs. actual results, event over event. Proof, not promises — and your reason to trust the leverage.
⬆️ One-click DraftKings
Import salaries, then export an upload-ready CSV or fill your reserved entries template in DK's Name (ID) format. Names map to upload IDs automatically.
We show our work
Every other tool asks you to trust their ownership. We publish ours. After each event, SlateSims scores its projection against the real DraftKings ownership and posts the error — head to head, even against your own model.
- Back-tested ~2.4% MAE across 20+ tournaments (leave-one-tournament-out).
- Per-event predicted-vs-actual archive that grows automatically.
- Bring your own projections and we'll score them side by side.
| Model | MAE (pts) |
|---|---|
| SlateSims | 3.05 |
| Field-average tools | typically higher |
Lower is sharper. We post this every week — the only ownership tool that does.

FAQ
Is this just another optimizer?
No. The optimizer is table stakes. SlateSims' edge is the ownership model — the sharpest, most-tested number in the space — wired into a full sim and contest-ROI stack.
Which site do you support?
DraftKings PGA today: salaries, IDs, status, exact payouts, and upload files. More sites and slate types are on the roadmap.
Do I need my own data?
No — everything pulls automatically. But if you have an edge (your own SG, odds, or projections), the Edge plan runs the model and sims on your numbers.
How does the free trial work?
14 days, full access, no card required. You'll get a full slate cycle — Tuesday projections through Sunday results — so you can see a real outcome before paying.
Can I cancel anytime?
Yes. Monthly, cancel whenever. Annual plans get two months free, and founding members keep their rate for life.
