Opinions of this "Hearts & Arrows Ideal Cut" chart?

I found this chart earlier today when I was googling "aga hearts arrows ideal". http://www.diamondjewellerystudio.com.au/cms/page/view/AGA-Cut-Chart-Brilliant

The two Whiteflash ACAs that I'm considering fit within those parameters, but I also found one on Blue Nile that fits for significantly less money.

Does that mean the Blue Nile diamond will demonstrate a good/"ideal" H&A pattern? Unfortunately, they don't have actual images of the diamond and I'm cautious about purchasing a stone without seeing images.

Think, how can you tell the optical symmetry of a stone from average and rounded numbers that is listed in a report? You cannot, the chart is meaningless w.r.t. if a stone has the optical symm to be called a H&A.

One can only check the accuracy of H&A pattern through a H&A image of the actual diamond.
