Cases

Measured results. With the same method before and after.

Cases are anonymised by default and published only when there is a valid comparison between a baseline and a final measurement, with source, date and evidence.

These cases are Portuguese, measured in the Portuguese market. The method transfers to other markets; the local source landscape has to be rebuilt for each one, and we would rather say so now.

How each case is measured

No percentage without a source.

Same method

Baseline and final measurement use the same prompts, engines, mode and number of runs.

Verifiable evidence

Every metric is computed from dated Periscopy exports.

Anonymised

Clients are identified by sector unless we hold written permission.

No extrapolation

Results apply only to the prompts, engines and period measured.

The next case could be yours.
