Formation Mutation Frequency
What it is
A straight count of hybrid-formation changes per match or season, read off shifts in the team's pass network (PN) shape — an objective, paper-derived companion to the qualitative mutation concept: not just that shapes change, but how often, and whether that frequency is trending up as the model beds in. Concept stage: needs a formation-change detection threshold so PN shifts within noise aren't over-counted.

Measured
Not from pass-network shifts (no player-tracking data here) but directly from the starting XI on each team sheet — a coarser but exact version of the same count. Across the 32 teams that played 4+ matches, the 13 that used three or more starting shapes averaged round 2.31 with 1.78 points per game, against round 1.68 and 1.41 for the 19 that stayed within two. Argentina reached the final having started in four different shapes. Spain, the champions, used only two — the clearest case in the whole report that this isn't a necessary condition, just an available one. Read the full report →
