Detailed Description

Time-Series tank fill levels start from the configured load, and a curve that needs more says so.

They used to start from the mass the curve consumes, so every run ended at exactly 0: on the LE4
(3) stand's engine at 578/578 psia for the config's 3.994 s the chart drew 7.55 kg of LOX for a
tank loaded with 6.61 kg (lox_tank.mass, the fire load), while the Flight tab on the same series
said the LOX runs dry at 3.50 s. Hand check: 6.611 kg / 1.8755 kg/s = 3.525 s.
