Reading the scores
Read the number as "how well this goes with Carlos", not "how good this sibling name is". Style, length, first letter and sound all feed into it, and rhyming pulls it down hard. 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. Carlos with Vincent or Raelynn does that.
