If you're interested I created a worksheet calculator to help me balance my resource production rates and made it public. Access it and save it to your documents to edit and use. It has a few buildings and resources to start and I will be adding more as I progress.
Basically you enter how many buildings of each you have (level 3 building = 3) and way over to the right it will tell you production per hour/day and how many buildings you need or over. Adjust your map to level these as needed. Very easy, try it out.
This is much better than Aurorah's Resource Calculator IMHO. Let me know if there's anything I can add or change to make it better for you.
3/5/12 - Revised to be much more precise.
3/9/12 - Revised to include storage level capacity. Now you can see how long it takes to fill a resource.
3/12/12 - Revised to take care of those pesky #DIV/0! errors, everything calculates with 0 values now.
