87.1% Light Return
Angles for R.I. = 1.62
65 facets + 12 facets on girdle = 77
2-fold, mirror-image symmetry
96 index
L/W = 1.200 T/W = 0.682 T/L = 0.568
P/W = 0.525 C/W = 0.186
H/W = (P+C)/W+0.02 = 0.731
P/H = 0.718 C/H = 0.254
Vol./W^3 = 0.374

Addition # 5 - I cut a lot of cushions, and there seems to be a lack of high quality fast ones that are fast to cut. The breaks can be cut in another order, also notice the C8 does not have a meet at the girdle. This is to absorb a little if your L/W is off. This can be cut in R.I 1.62 to 1.93 (89.3%) with no changes.
