Running an HCA calc using HRD certification

[ukstipe]

Quick question. HRD reports do not give total depth percentage. They do however give pavillion %, crown % and girdle %. If I add them up do I get something similar to a GIA/AGS total depth %?

It's even simpler...
Height : (Diameter1 + Diameter2)

E.G.

4.05 : (6.50 + 6.60)
=
4.05 : 6.55 = 0.618 = 61.8%
