No, I literally used the exact same resource value as the attacker had sent, in my sim. I did not give him any extra ships. All I did was give him a 20% tech advantage.
Notice how I said that I cut the number of BCs in half, and used the equivalent resources for cruisers, and then for LF. 150k BCs = 439,655 Cruisers = 3,187,500 LF. This scenario is a classic example of why cruisers are better fodder than LF.
