The Comp Constellation

Profile-shape similarity over six weighted feature groups, standardized within this season's 259 qualified hitters (288+ PA). Closer to the center star = more alike. xwOBA is deliberately excluded: this maps how hitters are built, not results twins.

Two profile shapes drawn over the same axes: overlap is what makes them comps, gaps are where they part. Stephenson, Tyler in signal, the comp in amber.

Weighted RMS z-distance over 6 feature groups, standardized within the qualified population; similarity = exp(-alpha * d^2), one global fixed transform. xwOBA excluded by design: this matches profile shape, not outcome twins. Descriptive, not predictive.
