Crankshaft Machine Group safety composite

Crankshaft Machine Group scores strongest on dart rate (safer than 74% of same-industry peers) and weakest on fatalities (safer than 50%), blended into one 0-100 breakdown against same-industry peers.

This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).
