I've got a design question....

I want to design a fast, basic generation CA with Ib engines.

Looking at the Construction Table, it looks like I'll have 67 hull spaces to play with. Max speed with Ia is 4, with a turn mode of 3. I will need 2 I per movement point.

As I understand it:

1. 8 Ia should give me a speed of 4

2. 10 Ia should give me speed 5.

3. 12 Ib should give me a tactical speed of 6 with a turn mode of 4, and a strategic speed of 3.

Is that right for a hull size of 67?
