Percentile profile

Each bar shows where Riverrock 2410 sits in the Angus New Zealand band for that trait. A longer bar means the figure sits nearer the top of the breed. It does not mean the figure is better. Several of these traits are held in the mid range on purpose, so read the bars against what you are breeding for.

Published figures

Neither end of a percentile scale is marked good here. Angus New Zealand is plain that some traits are best held in the mid range, and what you are breeding for decides which end you want. The bar shows where the figure sits on the scale, and the 2024 Born Average sits alongside as a reference, not as a pass mark.

Accuracy is how much information sits behind the figure. A figure with low accuracy can still move.
