Given the (extreme) level of technicality involved in all of this, and the fact that it generally requires a combined understanding of graduate level physics, physiology, and psychology, it is not so surprising that these higher and more exotic/abstract levels of optimization have been heretofore omitted--let alone have any presence in the popular awareness (hence the apparent reasonableness of the question). Fortunately, Magic-Flight's lead designer does happen to have this level of knowledge, and since they are all true geeks, they tend to go for this sort of thing. Magic-Flight has found that when implemented, such optimizations do make a difference, as user experience is able to attest. Magic-Flight figures that the overall magnitude of these second, third, and forth order effects is about 30%. The effort involved to get that additional yield, however, is at least 30X over that of the heating system design, and tends to require someone who has taken about 20 or so years of advanced schooling.
Gratings are usually specified by four parameters . Spatial frequency is the number of cycles occupying a particular distance (., 10 lines [or cycles] per millimeter). Contrast is a measure of the difference in luminance between the light parts of the grating and the dark parts. It is usually expressed as Michelson contrast:  the maximum luminance minus the minimum luminance divided by the maximum luminance plus the minimum luminance. Phase is the position of the graph relative to some standard position. It is usually measured in degrees (from 0 to 360 for one complete cycle) or in radians (2π for one complete cycle). Orientation is the angle the grating makes with some standard orientation (such as the y-axis in a picture). It is also usually measured in degree or in radians.
Specification: MIFAB Series T1400 6” wide pre-sloped trench drain system. Polypropylene drain body with integral top frame and 1/4" per section bottom slope, anchor flange with slotted tabs every 10” for rebar tie down and leveling, grate lockdown assembly, body support legs, interlocking ends, and radiused bottom. Standard with ANSI rated “Special Duty” lacquered ductile iron grates with a safe live load of over 10,000 lbs. (Note: Specify ductile iron frames for forklift applications.)
Function: Used in airports, car washes, malls and plazas, golf courses, factories, and any other facilities that require large areas of surface drainage. Chemical resistant polypropylene material provides for long life. V configuration channel design ensures maximum flow of water. Polypropylene support board prevents debris from entering trench body during construction.
