Experimenting with my Ger/CS/1905 design

I had not run my evolving general design of warships program against a relatively small ship, yet. I started with my scout cruiser design that was inspired by the "Super Swift" concept. I had not been sure as to what an appropriate hull weight factor might be, but from looking at March's British Destroyer book, it seems that something like 3.0 x 10^-3 or somewhat larger is about right. This is what my preliminary run looks like:
