calculating the melt duration (MD) as a function of a temperature (TMPF), a minimum melt duration (E1), an extended interval (E2), an anchor temperature (E3), and a step function (E4), according to the equation:

MD=MAX(E1,1+E4×INT((E3−TMPF)/E2)),

wherein INT rounds to a nearest integer and MAX selects a maximum.
