Is the efficiency of the unit (waste: product) temperature sensitive (i.e higher water temp = less waste)? my unit is rated at 50gpd but i know that is based on ideal conditions (60psi and 77'F).

couple of links (here and here) that show the roll off in output with cold water and reduced pressure below the ratings as well as something on rejection rates.
