	While speed modules inherently reduce the effectiveness of quality modules, there are cases where using a single speed module can increase the both the output rate of normal and quality items per unit of time (at the cost of more power consumption). This effect is best seen when using a single speed module in a beacon affecting a device with 4 quality modules installed: the increased output per unit time more than offsets the reduced quality % chance.		While speed modules inherently reduce the effectiveness of quality modules, there are cases where using a single speed module can increase the both the output rate of normal and quality items per unit of time (at the cost of more power consumption). This effect is best seen when using a single speed module in a beacon affecting a device with 4 quality modules installed: the increased output per unit time more than offsets the reduced quality % chance. This is a delicate balance though, as adding two speed modules to the beacon is almost always worse (though still better than no beacon at all).

Tau: /* Usage tips */ Added subsection regarding using speed and quality modules at the same time. Maybe it should be moved to a different subsection and include the actual calculations (which I can provide)?

	Another use for quality is decreasing the amount of buildings needed to perform the same production. This is particularly useful in a [[space platform]], where small, compact designs are rewarded with increased speed, as well as needing fewer rockets to build the platform.
