Maccor: 0.9 TCR = 26% of 334515 Instrument Manufacturing for Measuring and Testing Electricity and Electrical Signals BLS 3.3 · 3y Form 300A (see methodology below)

Maccor safety composite

Maccor scores strongest on total case rate (tcr) (safer than 54% of same-industry peers) and weakest on dart rate (safer than 29%), 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).
