[ZeonOne]

This formula is by no mean to be use as an exact duplicate of what Zen uses.

It is done with the fact that.
1) every endurance I gain, I seem to be getting 2% to 25% increase in training from about 5 endurance to 22 endurance.
2) every house upgrade I gain, I seem to be getting 9% increase per 100 happiness all the way to 1150 happiness.


Feel free to take what's here and add on with your finding. I am using this theory to help me to get a rough idea of where I would be when I do this or that. What's work for me might not work for everyone else.
