Reading the numbers

This style does not specify bitterness, so balance is set by the ingredients rather than by a target number.

Judges assess against the full written style description — aroma, flavor, mouthfeel and history — not only these figures. The BJCP guidelines carry the complete entry. What the numbers give you is the target to design a recipe against.
