It should be reversed...
Right now the more gens you have the faster it goes. Meaning its easier for people with lots of gens/looms to get more gens/looms.
I would think it should be easier to gen your first couple times, and get harder and harder as you try to gain more and more gens/looms - this is the way most leveling/acquisition systems work....the higher you go, the more difficult/grindy it becomes.
Never really understood the current system.
