L/W = 1.000 T/W = 0.562 T/L = 0.562
P/W = 0.523 C/W = 0.199
H/W = (P+C)/W+0.02 = 0.743
P/H = 0.705 C/H = 0.268
Vol./W^3 = 0.341

Addition # 5 - This works particularly well for medium colored materials. It is very fast to cut and does not have a lot of facets. This is really another "Money Cut". I use it a lot, when I want a cushion square that will deepen color a bit. This works well in R.I. 1.62 to 1.76 (89.9%) with no changes.
