A scenario is one contest in the Contest Simulation sheet. One run can hold several: a 10,000-entry GPP, the 2,000-entry GPP you plan to enter, and a double up. Each gets its own band in the lineups panel, so you compare contests side by side in one run.
Before you start
- Build a pool. See Run your first sim.
- Every field is explained in Contest Simulation settings.
Step by step
- Open the lineups panel and click Simulate (or Re-Simulate).
- Click Add scenario at the top of the rail. The new scenario starts as a copy of the default GPP, so it reads Same as Sim 1 until you change it.
- Open Prefill from Contest and pick the contest for this scenario. Confirm that the size, fee, and payouts match the contest.
- Repeat for every contest you want to compare.
- Rename, reorder, Duplicate scenario, or Remove scenario as needed.
- Click Run N Simulations.
- Read the panel. Each scenario has its own band with its ROI badge, its own picker, and its own selected lineups under it.
Controls that change the result
| Control | What it does |
|---|---|
| Add scenario | Adds a scenario with the default economics. Disabled when an entries file sets the scenarios. |
| Move scenario up / Move scenario down | Reorders the rail. |
| Duplicate scenario | Copies the selected scenario. Change one field to test one variable. |
| Remove scenario | Deletes it with an Undo toast. Disabled on the last scenario. |
| Scenario picker on the band | Fills that contest by its own method. See Select and rank after a sim. |
How it works
Every scenario is a separate simulation over the same pool, with its own field and payout ladder.
The pool-wide numbers come from one scenario: the one with the largest Contest Size, or the first of them on a tie. The Pool tab ranks by those numbers. A cloud build uses the same rule.
The panel's Entries Preview count becomes the total of My Entries across your scenarios once the sim runs. Three scenarios with 20, 20, and 1 lock the count at 41. Each band then selects its own share from the pool with its own picker.
Re-Simulate runs every scenario in the list again over the current pool. A scenario you removed keeps its last results until you run again.
Two scenarios with identical settings return identical numbers, so the rail marks them Same as <name>. A run sims at most 50 scenarios. Past 50, it sims the contest with the largest field, then the contests with the most money entered; the others fill without a sim of their own.
Compare a large GPP to a small one
- Keep Sim 1 at 10,000 entries.
- Add a scenario, click the 2K chip under Contest Size, and leave the payouts.
- Run both. The small field shows higher Win and Top 1% for the same lineups, and the Top 0.1% cell may disappear because a 2,000-entry field has only 2 places in its top 0.1%.
- Open the Pool tab. Every card lists both scenarios, so you see which lineups hold up in both fields and which only work in one.
Tips
- Name scenarios by what they test: Milly, Small GPP, Double up.
- Put the contest you will really enter first. Its band is the first you read, and its picker fills the most entries.
- Add a cash scenario to every run. A lineup with a high Top 1% and a low Cash% is a boom-or-bust build.
- Upload your entries file before you sim. You get a scenario per contest for free.
Troubleshooting
"Same settings as <name>. The simulation is deterministic, so this scenario will produce identical results. Change its contest size, entry fee or payouts to test something different." : change one field or remove the scenario.
"Scenario removed" with Undo : click Undo in the toast to bring it back.
A scenario row reads "failed" in the loader : that scenario's sim did not finish. The others still land. Check the scenario and click Re-Simulate.
