Fig. 8.

A schematic illustration of a performance variable stabilized by a two-M-mode synergy. A linear relation is assumed: F_X = k₁ * M₁ + k₂ * M₂. The solid slanted lines illustrate UCMs for different values of the performance variable. The ellipses illustrate possible data point distributions across cycles assuming that F_X is stabilized by a multi-M-mode synergy. The dashed slanted line corresponds to the orthogonal complement to the UCM. Note that linear regression analysis is only able to account for much of the F_X variance if F_X range is large
