Read this before you rely on any output. The PSC deficiency codes, action codes, CII
coefficients and ASTM constants in this build were read from the official published sources
listed at the foot of the page — they are not approximations. The calculators are still
simplified: they implement the core arithmetic, not every edge case, exemption or
charter-party variation. Verify against the governing document, contract or official
list before any formal submission, claim or fixture.
