426 E. 1St St. safety composite

426 E. 1St St. scores strongest on fatalities (safer than 50% of same-industry peers) and weakest on dart rate (safer than 32%), 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).
