HCA score - % vs Angles

[antcap51]

How come when I enter the percents of the crown and pav I get one score and then when I enter the angles of the crown and pav I get another? Which is more accurate and why the difference?

Angles are more accurate, so use those instead of percentages.

there is a clickable link under the big diamond diamgram on the hca page that says ''angles are more accurate'' if you click it, there will be more explanation.
