The GSI Method — How Poker Tournament Structures Are Rated

Why poker tournament structure matters

A tournament may be described as deep, fast or player-friendly, but those descriptions are often subjective. GSI replaces impression with a consistent measurement framework focused on the published structure itself.

The objective is not to judge the event as a whole. It is to make tournament structure measurable, readable and consistently rated.

What GSI analyzes

Each eligible structure is analyzed in depth by the GSI Intelligence Engine, which is frozen for the season.

The engine evaluates several measured components, weighted and cross-referenced, including Level Tempo, Time Above 50bb, Level Cost, Time Above 25bb and Initial Depth.

The same methodology is applied to every structure without exception. No tournament receives a different scoring model because of its brand, location, organizer or buy-in.

Exact formulas, weightings and thresholds remain proprietary in order to protect the integrity of the rating system.

What GSI does not measure

GSI does not rate the prestige of the event, the prize pool, the number of entrants, the organizer, the casino, the field or the player experience.

GSI rates the tournament structure — not the event around it.

Does the buy-in affect the GSI Score?

No.

A €100 tournament and a €10,000 tournament are measured using exactly the same structural rules.

The buy-in amount has zero weight in the GSI rating.

The GSI Score

Every complete and validated structure receives a GSI Score from 0 to 100.

The score is accompanied by a seven-star visual scale with proportional fill and a label ranging from Turbo to Skill.

The detailed GSI report explains the structure’s measured strengths and weaknesses and provides a level-by-level analysis.

The numerical GSI Score remains the primary rating.

One frozen engine. A reproducible score.

The GSI Intelligence Engine is frozen for the season. Within that season, the same structure must produce the same score.

A future season may use an updated engine. If the methodology changes, the new engine is applied consistently to every structure in that new season.

Closed seasons are never recalculated with a later engine. A 2026 score remains a score produced under the 2026 methodology.

A published score may also change if the underlying structure data is corrected or completed.

A standardized scope: the first 20 playing levels

The GSI Score is measured over the first 20 playing levels, excluding breaks. Levels beyond that evaluation window are not included in the score.

Using the same 20-level scope gives GSI a standardized basis for measuring tournament structures with different formats and durations under the same rules.

It also avoids giving disproportionate weight to very late-stage levels that may only be reached by a small part of the field.

GSI states this scope clearly: the score measures the defined evaluation window, not the entire published blind schedule.

Equal measurement means equal score

If two structures are identical over the 20 measured playing levels, everything GSI measures is identical. Their GSI Score is therefore identical, even if their blind schedules differ later.

This is deliberate. The same measured blind structure — whether used in a satellite, qualifier or recurring tournament — must produce the same rating.

A rating that changed between two identical measured structures would not be reproducible.

How ties are ranked

Structures with the same GSI Score share the same rank, following standard competition ranking.

If two structures are tied for first place, both rank first. Second place is skipped and the next structure ranks third.

Breaking a genuine tie would mean inventing a difference GSI did not measure.

Same measurement. Same rating. Same rank.

What the GSI Method gives players

GSI turns a published poker tournament structure into a score that can be understood within the same methodology used for every structure.

That makes it possible to explore rankings and understand how each structure is rated on the same measurement basis — without changing the scoring rules from one tournament to another.
