GE2studio methodology

Stable definitions.
Visible limitations.

A KPI is only comparable when its numerator, denominator, period and source remain explicit. This page sets out the public principles used in GE2studio demonstrations.

Interpretation principles

Before using a figure, check its source.

  1. 01Source

    Which occurrence or table produces the value?

  2. 02Définition

    Which events are included in the calculation?

  3. 03Couverture

    What proportion of the period and population can be used?

  4. 04Status

    Fact, estimate, simulation or assumption?

Calculation glossary

Six metrics explained simply.

The studio's contractual or regulatory conventions may require an adaptation. Every adaptation must be versioned.

01

Booking rate

Retained bookings ÷ published places

Measures booked demand at an explicit cut-off date. It does not measure attendance.

Specify how cancellations are treated and the period used.
02

Occupancy rate

Confirmed attendances ÷ available places

Measures actual use of the reference capacity.

Do not replace actual capacity with an arbitrary commercial capacity.
03

Taux de no-show

No-shows without cancellation ÷ retained bookings

Measures bookings that remained active but whose member did not attend.

Distinguish no-shows, late cancellations and unrecorded attendance.
04

Retention

Cohort members still active at the end date ÷ initial members

Tracks a defined cohort over time using a stable activity rule.

The time window and definition of active must be visible.
05

Churn

Members who left during the period ÷ members at risk of leaving

Measures departure using a consistent population and period.

Do not mix chosen expiry, non-payment and inactivity.
06

Simulation

Calculated scenario − baseline situation

Compares one or more assumptions using the same KPIs and a fixed baseline.

A simulation is neither an observed fact nor a guaranteed prediction.
Forecasts & simulations

An estimate is always presented as an estimate.

A projection must display its baseline, assumptions, horizon, coverage and, when calculable, confidence level.

Methodology exampleFictional data
Fait observé
71.4% attendance over the covered period
Assumption
+5 booking-rate points, other parameters unchanged
Simulation
Attendance and marginal cash receipts recalculated
Limitation
Seasonality and member response not modelled
Correlation ≠ causation

Two connected events do not mean that one causes the other.

A Coach, time slot or activity may be associated with a discrepancy without having caused it. GE2studio favours the terms “associated factors”, “contributing signals” and “assumptions to test” until a protocol supports going further.

Coverage & confidence

Two different concepts.

CouvertureWhat proportion of the expected data is actually available and usable?

It must consider the period, occurrences, critical fields and reconciliation quality.

ConfianceHow stable is the estimate given the model and available data?

It is displayed only when a calculable, documented method exists. Otherwise: “not calculable”.

Future benchmarks

No proprietary data before obtaining the right to publish it.

GE2studio will publish benchmarks only with a sufficient sample, robust anonymisation, established permissions and a documented method. No actual performance figure is currently presented as a market benchmark.

Put the method to the test
