An intermediate point may serve as width-changing point in a long straight line. Therefore, if it is removed, it will cause the line to have a uniform width and, as a result, lose (or gain) a bit of extrusion area. If you increase this you may notice slight under- (or over-) extrusion in between straight parallel walls, as more intermediate width-changing points will be allowed to be removed. Your print will be less accurate, but the g-code will be smaller.",
