I would LOVE to know if this proves out to be accurate in game. Maybe someone can test it before I waste my 600+ cruisers on it

That's a good thread. I like the part where the devs casually contradict a big part of what their tutorial says about combat...

Revised my script, the magic number is 561 cruisers.
