- Runs with over 15% spread or steadily climbing timings are excluded from the public aggregate as likely noisy or drifting.
Field notes
The method section distinguishes manufacturer bandwidth specifications from measurements collected across browser and GPU runs. It describes leaderboard rows as medians rather than personal bests, and says noisy or drifting runs are kept out of the aggregate. Model-speed figures are framed as ceilings, not promises, with memory limits inferred because the browser does not report the GPU's available memory.
