Jonaco Machine: 2.4 TCR = 73% of Machine shops BLS 3.3 · 3y Form 300A (see methodology below)

Jonaco Machine safety composite

Jonaco Machine scores strongest on dart rate (safer than 75% 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).
