Reading the scores
Read the number as "how well this goes with Isabel", 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
A sibling set works when the names feel related but not identical: a shared era or style, but different opening sounds and different endings, and no rhyme. Isabel with Damian or Aaliyah does that.
