Reading the scores
The number by each sibling name is how well it fits Octavia — roughly 5 to 99, higher is better. It rates the pairing, not the name on its own. How the score works.
What makes a sibling set work
The test is calling both names across a park. They need to start with different sounds so they do not blur together, be about equally well-known so one does not feel like an afterthought, and share a style so they sound like a pair you picked on purpose. Octavia with Emilio or Evangeline does that.
