96 index
L/W = 1.330 T/W = 0.833 T/L = 0.626
P/W = 0.466 C/W = 0.131
H/W = (P+C)/W+0.02 = 0.618
P/H = 0.755 C/H = 0.213
Vol./W^3 = 0.440

Addition # 4 - The 24/72 index float, the P7's can be adjusted for yield. A preform is a very good idea, this is not an easy cut, especially the first time. it works well in lighter materials, 1cts+. Works in Topaz also… Cut this in R.I. 1.62 to 2.14 (84.6%) without changes.
