HCA question

[atroop711]

When putting in your numbers into the HCA...do you put the Crown and Pavilion PERCENTAGE? or the ANGLE? and WHY would you do one over the other?

thanks

angles are more accurate.
When you put the % in it converts them to angles which is less accurate than when the angles are put in.

Angles. It say angles are more accurate at the bottom, because if % is input, simple trigo is used to recalculate back the angles and ploted on the chart, and some assumptions and rounding off errors are made in this calculation.
