From: The Big Nowhere
I know that a lot of work has gone into figuring this out, and I give you praise for it, but...
I simply am not going to number crunch and try to figure out the exact perfect formula. Anymore I just design my designs, mod the game files to get the AI templates to match, and be happy with it.
That is the key though, you need to be sure to adjust the AI design templates to match your own so you can keep some balance to the game. I still do manual designs on my own ships, but I try to have templates that would be very, very similar to how I'd build them on my own. That is, trying to keep the defense/firepower/speed in balance (not perfect balance mind you, just competitive).
I think for some people (like me) the game is a lot less fun when you spend too much time an getting everything perfectly efficient. It's just a personal preference thing.
