What if we had an Coolant Efficiency upgrade? like what the Dye Mixer has with its Efficiency Upgrade. Maybe Level 1 output is 1 (current), and Level 2 output is 2, and Level 3 output is 4, to be in line with the Advanced operators doubling their operations with each speed level upgrade. I do not think Luminol needs an efficiency upgrade, since that is already efficient with the Dye Mixer.
