Indeed, I was trying to work with the ideas already being tossed around, and build on them. That being said, I do really like your idea. What I was hoping to build was something self-maintaining like what you're suggesting (as I explained in my follow up post to her), but it seems your idea would do it more easily. Perhaps the game could auto-calculate the potencies and build up an optimal rotation based around thousands of calculations of different scenarios. A bit like "machine learning" and AI.
