Ca197 Nsi-Mi Technologies: 0.9 TCR = 27% of Instruments for Measuring and Testing of Electricity and Electrical Signals BLS 3.3 · 2y Form 300A (see methodology below)

Ca197 Nsi-Mi Technologies safety composite

Ca197 Nsi-Mi Technologies scores strongest on total case rate (tcr) (safer than 52% of same-industry peers) and weakest on dart rate (safer than 16%), 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).
