Aloha,
Not ALL of our test ships turn out this way, and considering that our testers have their own ships on their account that they will want to play, they don't play an over abundance of battles in these test ships.
We have to gather data from regular Random battles, this is why they drop into these battles.
That being said, keep in mind many of our STs are very good players with a lot of experience, sometimes, even an underpowered test ship can overperform in the hands of the right player sometimes.
