How we verify our numbers
Every equity, out-count, and solver frequency on PLO.com is computed by software we built and own — and checked again before anything is published.
The equity engine
The same engine that powers our equity calculatorcomputes the numbers in our articles. It enumerates Pot-Limit Omaha's exactly-two-hole-cards rule exhaustively — every legal two-card and three-card combination — and its hand evaluator has been verified against an independent reference implementation across all 2,598,960 five-card hands, reproducing the known poker combinatorics exactly.
The solver library
Our range and frequency data comes from MonkerSolver solutions we ran and decoded in-house, covering 6-max and heads-up games from 12bb to 200bb, including rake-adjusted trees. When an article says a hand class opens some percentage of the time from a position, that number is read directly from the solve at a pinned decision node — see our 6-max opening ranges reference for the data itself, or explore it interactively in the solver.
The validator
Before any article is published, an automated validator re-derives every claim it makes: each stated made hand is checked under the exactly-two rule, each draw's outs are enumerated card by card, and every equity-calculator link in the text is executed through the engine. If the prose contradicts the math — a "wrap" that is actually a made straight, an equity claim its own linked calculation disproves — the article is rejected. There is no override for factual errors, for automated drafts and human editors alike.
What this means for you
When you read a number here, you can check it yourself: equity claims link to the calculator pre-loaded with the exact spot, so one click reruns the computation we ran. If you ever find a number that looks wrong, it either has a link that proves it — or we made a mistake and want to know.
Where numbers come from, in one line
Equities: our engine, exact enumeration where feasible. Frequencies: our decoded solves, node-pinned. Everything else: qualitative on purpose — we would rather say "most of the time" than invent a decimal.
