Marcus Vance
Contributing Writer, Math & Logistics
Marcus writes the guides on this site: the freight class explainer, the density walkthrough, the NMFC code primer, and the piece on how class actually moves an LTL rate. He tends to start each guide from a worked number, a specific pallet, a specific rate, rather than an abstract definition, since that's closer to how the question actually comes up at a dock or a planning desk.
Across the Encore Editorial network his beat is technical and quantitative content: unit conversions, classification systems, and the kind of math a reader wants double-checked rather than summarized. Questions or corrections on anything under his byline go through the contact page.
Chris Terry
Founder & Site Owner
Chris built the Freight Class Calculator and the Density Calculator, along with the NMFC reference table both tools rely on. He owns the accuracy of the underlying density-to-class formula and signs off on any change that touches the math.
Full detail on how the figures are sourced, checked and corrected is on the editorial standards page.
