Where do you place the markings for middle third at?

[@TheDBZCollector]

kind of embarrassing . if you apply 125 and 175 psi/min. how is the reading 1500 to 2100 lb/min. i'm confused.

[@atreyrsps]

The load is applied over 12 in^2, so to convert from psi to lb you multiply by 12. 125*12 = 1500 and 175*12 = 2100
