Porterville safety composite

Porterville scores strongest on dart rate (safer than 83% of same-industry peers) and weakest on total case rate (tcr) (safer than 10%), blended into one 0-100 breakdown against same-industry peers. A missing measure drops out and redistributes its weight rather than deflating the score. This is a per-dimension breakdown, distinct from the single letter grade above it (which weights TCR alone against the BLS industry benchmark).

Porterville has fewer employees than the Bus operation, school and employee median and a higher injury rate than the industry's median TCR of 4.3.
