Asked the same question twice, the models moved their own first choice 67% of the time. The leader still held in 46 of 60 readings (20 categories at three buyer sizes).
Twenty categories were asked again three days after the edition run, with nothing changed: the same prompts, the same model versions, the same settings, one buyer segment, six framings, fourteen models, 1,680 answers. Whatever differs between the two runs is noise, and the noise is what this page measures. That is the reason the index asks every question six ways of every model rather than once: on its own, one ask moved 67% of the time; eighty-four, read together, are what the index reports.
Model by model
MiniMax M2.5 changed its first choice most often, 82% of its 82 pairs; GPT-6 Luna least, 40% of 77. Pooled over every model and question, 67%.
A flip is the same model, the same question, a different first choice a few days apart. It says how much one answer can be trusted on its own, and nothing about why the model answered as it did.

In 46 of the 60 readings (20 categories at three buyer sizes) the same product led both runs. Where the leader changed, the two products were within 12 points of each other in the edition run.
The share floor
From the next edition on, a product's change in share counts as movement only when it is larger than 11 points, and a new leader is reported only when it clears the old one by more than that. Nine repeats in ten move a leader less. The floor is measured again with every edition and the method page carries the rule: how the floor is measured.
