Confused...abt Holloway Cut Adviser vs Tolkowsky Ideal Proporitons

[albetan]

Hello

When i enter the Tolkowsky Ideal Proporitons dimension (from Tutorial\AGS Idea Cut)
into the Holloway Cute Adviser, it shows wrong data or girdle is dangerously thin.

Thought i should be expecting some better grade than that ?

Looking at the figure, you''ll notice the girdle is 0%. On the Tutorial page, in the text, there''s a "here" link toward the bottom of the page. If you''ll click on that, you''ll find the explanation.

"My girdle article shows how adding a girdle changes Tolkowsky''s Diamond Design.
The thin curves in figure 3 show diamonds whose thin parts of the girdle are 0.0 % of their diameter (at the "scallops"), and whose thick parts of the girdle are 1.7 % of their diameter (at the "mains"). These diamonds are fragile, because of their thin girdles."

There''s more information about girdle thicknesses there as well.
