From our data, it appears to be pure RNG. The only thing you can really do to improve your chances is sacrifice more Lalas to RNGesus.

For unlocking things faster, I recommend making a ship with a Viltgance rigging and Bronco Aftcastle (which would have absolute maximum speed) and using it to hit the sector as fast as possible. The more hits, the more chances to unlock.
