Upon viewing the sight of Pabu lighting up at dusk, Phee describes it as "spectacular," which Tech says "is one way to quantify it." To quantify means to measure something in raw numbers. He likely meant "qualify," which is to explain something in descriptive language. Someone as intelligent as Tech should know the difference.
Tech estimates that it will take "several rotations" to repair the damage to the city. In Star Wars, a "rotation" is one day (earlier in this episode, Cid noted that the Bad Batch hadn't been in contact with her in 20 rotations). The damage is far too extensive to be repaired in just a few days.
