I think the geometric series this mod uses fits the concept of a Core Miner very well. This way, the returns from the first few added miners are much more rewarding, while the total return for a theoretical infinite number of miners approaches a finite number. Unless you set the configurable diminishing rate too high, this mod allows for a nice rebalance without making those miners completely overpowered.

A short question:
In the information, it says that the average efficiency for 20 miners with a diminishing rate of 0.1 would be 0.472 instead of 0.43921. I was wondering why that would be the case?
