Engine Movement bonuses

Are you talking about a bell curve sort of deal? Where you start out low movement low supplies then climb in movement and supply consumption and finally supplies fall but movement stays unchanged. Ok maybe a bell curve on the supply side would be more accurate. I only ask because there would be a point on any bell curve where future supply consumption and movement provided make it not worth the expended cost of additional research. So players would lose incentive to develop the higher levels.
