Residual map of the leading paired-comparison bimension

Objects placed in the leading bimension plane. Reading round the swirl, an object sits “upstream” of those it over-beats relative to the fitted locations; a clear rotational arrangement is the second attribute, a formless blob near the origin is noise. Point size grows with the object's location on the primary scale.
