⬡ Constellation radar — co-movement inside your portfolio

ETVI and your Grid Collision Constellation co-move at 0.81 over six cycles — ETVI leads. When ETVI recalibrates upward, the constellation's lagging member (Transmission Buildout) has followed within one cycle, five of six times. Licensees of one are prompted with the other.
