100320: 4.5 TCR = 131% of industry BLS 3.4 · 3y Form 300A (see methodology below)

100320 safety composite

100320 scores strongest on total case rate (tcr) (safer than 53% of same-industry peers) and weakest on dart rate (safer than 32%), 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).
