These are current DOE test ratings, not the old box numbers. Since 2019, capacity is measured at 65°F (Appendix X1). The old 80°F test rated units much higher — a unit sold as "50-pint" under the old test now certifies around 30-35 pints; a "70-pint" unit around 50. If you're shopping by a number you remember from a box, it's probably one tier lower here.
