Some questions for your FAQ:
What, exactly, does Crackerplier do? At 2+mil DPS it seems to make little or no difference.
What upgrades are non-idle only? It seems that Berzerk on mower is one. Are Ship Speed and Paddle Speed others?
There seems to be a CPU limit on the DPS that can be achieved. Is this quantifiable? [Edit: Actually, that might be my answer to Q1]
