At the moment I use some slightly modified benchmarks (CAI-vs-CAI and Human-vs-nullAI) to run my local tests with the benchmark tool. More infos on how benchmarks and startscripts work can be found here:
http://zero-k.info/Forum/Thread/4906 . I havent figured out how to pass startscripts directly to spring, but I didn't do a real search on the topic.
While testing I found some things I have to modify before sharing. For example, with a LV factory CAI mostly builds wolverines as arty, but almost no of the other type. The factory selector for later factories could also use some tweaks.
Indipendently of that I think the way defences are built should consider enemy positions (watching CAI vs CAI, youll almost always see a time where an AI starts to spam defences at the back of its base near the map edge while its front is falling apart) and I think current CAI cant build ships (I have to realy look into that, but I did not see any ships while browsing the sources).
