Acutally, I have 50 planets that form my production core with about 10 factories, an advanced farm and the rest stock exchanges. All other planets have the initial colony an advanced farm and everything else stock exchanges. The only exception is a single quasi research planet which still has a lot of stock exchanges on it.
I'm not sure but I don't think Mind Control Center compounds all the other bonuses. I think it just gives a straight 100% bonus. My total economic bonus from stats and graphs is ~390%. This would include resource mining, racial ability, the Federalists bonus, the MCC, tech ability bonuses plus whatever few percents I may have picked up from anomolies. I think only the 30% economic bonus from Federation government isn't included in this.
Clearly, the numbers would be lower in 1.3 because of the reasons you give, however all my pop (except a few civilization capitals) is at 15B. In v1.3 you'd be able to stabilize at 19B which would gain some of the differences back. Also, the luck of the draw in how many economic resources you get is big. I've found 6 is about average, 7 is common but in this case I got only 5. Plus I could have been more efficient in a lot of ways.
My point in posting the screenshot was not to crow about how great a player I am. I'm sure there are many better players out there. My point was in response to the following post about how the v1.3 changes stopped people from having 79% taxes with no morale buildings.
WWW LinkIn my opinion, the farm / morale changes only nerfed the ability to have high pop planets with no significant change to the issue of 79% taxes with no morale buildings.
