Ahh, I love quadruple-blocks
However, since you can only buy three normal generals from the tavern,
and since all generals in your images are yours, how did you do it?
Did you invite a friend to help you, or did you use a battle hardened general in one of the blocks?
I would certainly not recommend the latter...
Your current setup for camp 5 would indeed only last 4-9 rounds (average 5.1).
1R 9S 190C would last 5-10 rounds (average 7.5).
