Yes I understand assembly, machining, production times...blah blah blah. I still dont see where you get a pentalobe settles faster? You have 5 lobes that have to align perfectly before it settles in, a philips will essentially settle itself due to the angles and with spring pressure against the driver it will settle faster and drive. And were not talking ft-lbs here, its a 1/16" screw.
Has to do with organic geometry. Lobe shapes and spline paths take the least amount of energy to adjust to another lobe or spline. Basic geometries take more energy and thus are not see often in nature. We continue this further, I'm going to start billing my consulting rates.
