"level 1 Active-EM scanning and level 0 everything else. It also says that a level X scan will beat a level X cloak. But if that's so, why do the cloaks start at level 2? Why isn't there a level 1 cloak?"
Think about it a little more using just that paragraph.
Ships start with level 1 scanning. Level 1 scanning beats level 1 cloak. Therefore.. level 1 cloak = useless.
