Reading the scores
Read the number as "how well this goes with August", 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. August with Silas or Ruby does that.

Common questions
What names go well with August for a sibling?
For a brother: Silas, Rowan, Wesley, Felix.
For a sister: Ruby, Stella, Luna, Iris. These share August's style and level of familiarity without rhyming or starting with the same letter.
Should a sibling name match August?
It should feel like it belongs to the same family as August, not like a matching set. That means a shared era or style — August reads as nature and vintage, so lean that way — but a different starting sound and ending. Names that rhyme with August or also start with "A" get fewer points here.
Does August need a sibling name of the same origin?
It helps but is not required. Another Latin name (like August) gets a small scoring bonus because shared roots read as deliberate, but a strong style match with August matters more either way.
How is the match score for August worked out?
