Twitter 1 10th: 1.2 TCR = 41% of industry BLS 3.0 · 4y Form 300A (see methodology below)

Twitter 1 10th safety composite

Twitter 1 10th scores strongest on total case rate (tcr) (safer than 88% of same-industry peers) and weakest on fatalities (safer than 50%), 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).
