Advanced Flow Engineering, Inc.: 4.4 TCR = 82% of Filters (e.g., air, engine oil, fuel) automotive, truck, and bus, manufacturing BLS 5.4 · 2y Form 300A (see methodology below)

Advanced Flow Engineering, Inc. safety composite

Advanced Flow Engineering, Inc. scores strongest on dart rate (safer than 68% of same-industry peers) and weakest on total case rate (tcr) (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).
