The Grading Grid and WROIR

This is the Grid I will use to rate hobby boxes and cases. The numbers on the Grid represent a total average Weighted Ratio of ROI. I may adjust the Grid in the future as I fine tune the calculation. Feel free to email me with any comments or suggestions.

2.01 and Above..........A+
1.88-2.00...............A
1.74-1.87...............A
1.60-1.73...............B+
1.46-1.59...............B
1.33-1.45...............B-
1.19-1.32...............C+
1.05-1.18...............C
0.92-1.04...............C-
0.78-0.91...............D+
0.64-0.77...............D
0.51-0.63...............D-
0.50 and Below..........F

Weighted ROI (Return on Investment) Ratio is the WROIR
