Methodology
How to Read These Numbers
These percentages are coaching estimates informed by published research, not measured probabilities from a single dataset.
EstimatedThe Simplex Motus Position Transition Roadmap, Volume 2 supplies the baseline, Gi, and No-Gi values. The overall split groups the baseline outcomes by which role they favor. Published studies provide context for the estimates, not direct measurements of these exact exit percentages.
Gi means grappling with a uniform jacket and pants; No-Gi means grappling without that uniform. “Overall” is the roadmap's baseline estimate, not an average calculated from the two formats.
Limitations
The cited studies provide context, but do not report these exact position-exit rates. Without raw counts or a reproducible calculation for the displayed percentages, these estimates should not be treated as measured frequencies or predictions for a particular match.
Research trail
Evidence & Sources
The original roadmap, Volume 2 (PDF) provides the displayed baseline, Gi, and No-Gi values and assigns the references below to North-South. Public studies do not track every specific position exit shown here. Where direct measurements are unavailable, the roadmap uses evidence-constrained coaching estimates. No sample size, raw counts, or reproducible calculation for these exact percentages is provided in the document. Treat them as a directional training guide, not observed rates or a prediction for a match.
